Fizz E (bug vs cass W)

Fizz E can be canceled midair by (Misama) of cassiopia (w) not sure if its the only reason , i were playing vs cass veig naut blitz lucian , and every teamfight i use my E it activates and once im on midair i cant move i cant cast anything (most likely misama is the only reason) cuz i fought vs all of them normally with no glitch
