I'm not sure why it happens however you can solve it by putting the ScrollView inside a panel.
B4X:
Sub pg_KeyboardStateChanged (Height As Float)
Panel1.Height = Min(Panel1.CalcRelativeKeyboardHeight(Height), pg.RootPanel.Height - 10 - Panel1.Top)
svUserInfo.Height = Panel1.Height
End Sub
I recommend you to delete all the designer script and use anchors instead. It will simplify your layout.
