FS Academy evo?

Was doing the evo and made sure not to add any other evolutions outside of FS academy. Did the 8 playstyles and added the weak foot and skill moves and playstyle +.  Went to add the last weak foot upgrade to 5 stars and it says “upgrade up to 4 stars”.  Is this a glitch or did I upgrade in the wrong order now making the 5 stars weak foot upgrade unobtainable. (If I messed up and did the 5 star upgrade before the 4 star why wouldn’t it upgrade automatically to take it to 5 stars anyway?) anyone else have this problem?
