Leveling character issue

I’m new to posting in the forum for killer instinct, but I am definitely no stranger to this game. Recently I’ve been experiencing issues with leveling on kan ra. After playing for a bit a leveling up from 8 to 27 with him I closed ki, the next day i opened the game to play I noticed he was some how magically lvl 8 again🤔. It’s been happening for the past week or so. I haven’t been wanting to play anyone else except for him. Also I have no Idea if any other characters have been affected or anyone else is having this issue…well I guess that is why I am posting this. Thanks in advance for any info you guys have😀
