Unlocking titles problem!

[Jubaru]

Hey, hopefully someone has knowledge on this. Basically I have competed most character’s combo challenges to 100% but with Ayane and Kokoro i can’t buy the title that comes with completing it .
Still showing as ‘????’

The same thing recently happened to me as well. There is apparently a bug from the last update that prevents titles from unlocking even if you met the conditions. It will be fixed in the next update and any titles that should have been unlocked will.
