Hello.
Here is my interface for Quest UI:
It’s a little bit a big suffering to deal with the UI layout lol.
It seems to have its proper life.
I hope Unity plane an exorcism to fix that lol…

Edit:
If like me sometime your scrollbar turn crazy and start at the bottom, maybe it could be a good idea to revert locally the guilty.
In the Core object, select override and revert only your dommed scrollbar 
Select on of your scrollbar and another panl wiil display
Choose Revert, locally for each item wich doesn"t work properly in gamemode.
Sam override everything but sometime it can turn crazy all my UI interface lol.
I prefere snipe the Guilty and let the innocent live
Schuss
