I reported this via support but got fobbed off. When you change your equipped disk and then do a quickfight it changes the disk on ALL modes to the one that was not equipped.

On this vid I am swapping Eda’s disc.
She has Me disk equipped in main
I go into the fight which has defaulted to Fa Disk
I change it to Me disk
I quickfight
After fight its reverted back to Fa Disk
Its also changed the default to Fa Disk
This will have changed in all game modes
It only sets the disk correctly if I manually fight. If I do a quickfight after changing the disk in any mode then I gotta fix them all.
