Save Failed System Storage Access Error Occurred Help

[SnakeSlippers]

I tried installing Farooq APA mod. I also tried switching slots, none of it worked.

I replaced the slot it's supposed to be in back to normal

I deleted the new slot I tried.

His name keeps showing up in game no matter what I do

I installed empty pofo's and movesets, to slow 305 (Farooq)(Pac Plus). I replaced slot 238 Big Bossman back to BBM's stuff. 

 

And I get the "save failed system storage access error occurred" error when I hover over his name in Edit Superstars
