Why does Fragment exit animation not work?

I'm adding fragment with animation from bottom to top and then it should go from top to down when back is pressed or when popBackStack() is called.

val confirmFragment = ConfirmFragment.Companion.newInstance(item)
val transaction = MainActivity.getMainActivity(context)!!.supportFragmentManager.beginTransaction()
transaction.addToBackStack(tag)
transaction.setCustomAnimations(R.anim.slide_in_bottom, R.anim.slide_out_top)
transaction.replace(R.id.over_view, confirmFragment, tag)
transaction.commit()

ExitAnimation (xml)

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
    <translate
        android:duration="700"
        android:fromYDelta="100%"
        android:toYDelta="0%" >
    </translate>
</set>

EnterAnimation (xml)

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
    <translate
        android:duration="1700"
        android:fromYDelta="0%"
        android:toYDelta="100%" >
    </translate>
</set>

The enter animation works but when the fragment exists it doesn't work

Remove the set tag in your xml code .

Change to this .

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="700"
    android:fromYDelta="100%p"
    android:toYDelta="0%p">
</translate>

And 

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="1700"
    android:fromYDelta="0%p"
    android:toYDelta="-100%p">
</translate>
