Lost all savedata when connecting 2nd controller

Today i'm realized all my old game savedata is gone, i'm checking last savedata, it's bayonetta, on saturday, the day i'm connected 2nd controller (and create new user profile to use with 2nd controller).

So this is bug or something?
found one guy had same problem like me : https://www.reddit.com/r/ps4homebrew/comments/8vf71x/ps4_mirahen_save_data_disappeared/
