Several errors that I found in the Creator

I want to point out several errors or inconsistencies that I have encountered.

The first is that when I enter another screen and return to the previous one, when I call a Side Menu item that is a notification, it does not show it.

The other error is that when I try to disable or false a Vertical Arrangement that is visible, it keeps the screen filling, and those that I activate only occupy the available space. This happens to me in Android 5.1, in Android 7 it does not happen to me, I do not know that other Api have that problem.

Apparently, when you activate Scroll on the screen, all the elements go on top.
