Conditional Procedures using Advancements not working.

Hi! I've been trying to make a semi-progression kind of feature to my mod which allows the player to unlock other aspects of the mod, like having to research something and get the achievement to unlock the item or gui etc. With this concept I have buttons and labels in a gui that will only appear when the player unlocks the corresponding advancement but the conditional procedures are not working. The conditional procedures are very simple just "If has completed ______ advancement =true, then (return true) then a (return false) block under it. I've made conditional procedures before and they've worked so i'm a bit stumped on why these aren't working. I'm using 1.19.2 and 2023.2 version of Mcreator.
