Maintained Buff Window Scrollment Help Needed

[MirageKnight]

After GU53, I can't figure out how to make maintained buff window to scroll to show all 30 buffs. It was working fine before GU53.

This is because I have almost 18 maintained buffs and I would like to make maintained buff window to scroll down to show blank 12 buff slots before combat so I can keep track of my debuff/buff in combat.

Currently, this xml only allow to scroll down when I made window small for some reason.
I have tried to resize and so on but can't figure out how to do this myself.

I appreciate any help Thank you.
