[Bug] Ability on Bar Replaced With Meld

So this has been happening for a while and I am not sure what is causing it, but occasionally yet consistently doing certain activities like turning in Unique/Untradeables for GC seals causes the ability on hotbar 1 to be replaced with the Meld Materia action, regardless of what ability was there, and regardless of what class I am on. Some other times it happens randomly like after talking to NPCs for quests. Locking the bar from being changed has no effect on this bug, and it doesn't happen 100% of the time, probably about 40%.

We appreciate you taking the time to report this error to us. However, there are still some details that we need to collect from you before we are able to investigate this properly. Please use the bug reporting template found Here, and make another post. Thank you!
