Label not showing properly in scrollview section

The last few lines of my label are not showing. I want my label to show properly on my screen using ScrollView widget I tried this but ScrollView is not working unless it has more few lines but as I increase the lines And as I scroll again last lines not come up properly. In short, I want as my length of text increases the scroll view shows properly every line of my label and the space between paragraphs also not showing

here's my code of .kv file

ScreenManager:
    id: screen_manager

    MainScreen:
        name: 'main'

        NavigationLayout:

            ScreenManager:

                    MDToolbar:
                        title: "Story"
                        anchor_title: 'left'
                        pos_hint: {"top": 1}
                        elevation: 10
                        left_action_items: [['menu', lambda x: nav_drawer.set_state()]]

             MDNavigationDrawer:

                    A boy and a girl were playing together. The boy
                    had a collection of marbles. The girl has some
                    sweets with her. The boy told the girl that he
                    would give her all his marbles in exchange for the
                    sweets with her. The girl agreed.

                    The boy kept the most beautiful and the biggest
                    marbles with him and gave her the remaining marbles.
                    The girl gave him all her sweets as she promised.
                    That night the girl slept peacefully. But the boy
                    could not sleep as he kept wondering if the girl
                    has hidden some sweets from him the way he had
                    hidden the best marbles from her.

                    Moral of the Story :

                    If you do not give 100 percent in a relationship,
                    you will always kept doubting if the other person
                    has given her / his hundred percent. This is applicable
                    for any relationship like love, employee –

                    feeling that last long

I noticed that you were doing the same thing with AboutUs, so I also modified that so that all of its layout is now in the <AboutUs>: rule. Since your ScreenManager is now in a different rule from your Screens, you cannot access it using its id (ids are only valid within the same rule). So Screen changes can be done using app.root.current.

I think that the screen_manager: app.root is not working because the app is not yet available when that expression is evaluated.
