Visual Errors in Scrollview container

Hi I’m new to using this haxe ui stuff (and still kinda new-ish to programming in general), but I was wondering if there’s an explanation as to why I keep getting these visual errors whenever I use certain components in a scrollview container.

I’ve noticed these errors using the following components and containers:
-number steppers
-textfields
-list views

I’m not sure if this is a user error or something else.
