Woocommerce single variation price displaying not as intended

Question

On our woocommerce site we have a price range that is from the lowest price to the highest price.$2 - $600 for example. Then we have a 10% discount on the whole range so it will then display as strikethrough the whole range $2 - $600 and display $1.80 - $540 for example.

When I now select a single variation it displays $540 - $0 for example. But I only want the $540 to display and the - $0 must be removed. I will show a screenshot example.

I have tried various filters but the actual output of a single variation price have not changed.

add_filter( 'woocommerce_get_price_html', 'custom_price_format', 10, 2 );
add_filter( 'woocommerce_variable_price_html', 'custom_price_format', 10, 2 );

function custom_price_format( $price, $product ) {

    // 1. Variable products
    if( $product->is_type('variable') ){

        // Searching for the default variation
        $default_attributes = $product->get_default_attributes();
        // Loop through available variations
        foreach($product->get_available_variations() as $variation){
            $found = true; // Initializing
            // Loop through variation attributes
            foreach( $variation['attributes'] as $key => $value ){
                $taxonomy = str_replace( 'attribute_', '', $key );
                // Searching for a matching variation as default
                if( isset($default_attributes[$taxonomy]) && $default_attributes[$taxonomy] != $value ){
                    $found = false;
                    break;
                }
            }
            // When it's found we set it and we stop the main loop
            if( $found ) {
                $default_variaton = $variation;
                break;
            } // If not we continue
            else {
                continue;
            }
        }
        // Get the default variation prices or if not set the variable product min prices
        $regular_price = $product->get_variation_regular_price( 'min', true );
        $sale_price = $product->get_variation_sale_price( 'min', true );
        $regular_price_max = $product->get_variation_regular_price('max', true);
        $sale_price_max = $product->get_variation_sale_price( 'max', true );
    }
    // 2. Other products types
    else {
        $regular_price = $product->get_regular_price();
        $sale_price    = $product->get_sale_price();
    }

    // Formatting the price
    if ( $regular_price !== $sale_price && $product->is_on_sale()) {
        // Percentage calculation and text
        $percentage = round( ( $regular_price - $sale_price ) / $regular_price * 100 ).'%';
        $txt = " - ";

        $price = '<del>'.wc_price($regular_price).'</del><ins>'.$txt.'</ins><del>'.wc_price($regular_price_max).'</del><br><ins>'.wc_price($sale_price).$txt.wc_price($sale_price_max).'</ins>';
    }
    return $price;
}

add_filter( 'woocommerce_show_variation_price', 'filter_show_variation_price', 10, 3 );
function filter_show_variation_price( $condition, $product, $variation ){
    if( $variation->get_price() === "" ) return false;
    else return true;
}

That is my filters I currently have on my functions.php file.

Here is a screenshot of my problem:

I want the range variation price to show with the sale price and regular price with a strikethrough but only a single price to show as soon as you select a variation.

add_filter( 'woocommerce_get_price_html', 'custom_price_format', 10, 2 );
add_filter( 'woocommerce_variable_price_html', 'custom_price_format', 10, 2 );

function custom_price_format( $price, $product ) {

}
// 2. Other products types
else {

// Formatting the price

    $txt = " - ";

    //Check if Sale Price Exists
    if(wc_price($sale_price_max) !== 0.00){
      $price = '<del>'.wc_price($regular_price).'</del><ins>'.$txt.'</ins><del>'.wc_price($regular_price_max).'</del><br><ins>'.wc_price($sale_price).$txt.wc_price($sale_price_max).'</ins>';
    } else {
    //else return price without second sale price
    $price = '<del>'.wc_price($regular_price).'</del><ins>'.$txt.'</ins><del>'.wc_price($regular_price_max).'</del><br><ins>'.wc_price($sale_price).'</ins>';
    }    
}
return $price;
}

Please try the above code and let me know.
