[Unanswered]  Zeta-s won’t stay in place

i recently bought the hasbro turbo spryzen s4 set, and for some reason all of a sudden my zeta-s driver won’t stay in place. the only mode that still works is the slingshock mode, the worst one.if i try to put the performace tip in stamina or attack mode, even when i push it down to lock in the mode, it still rotates around unless it is on slingshock mode. has anyone else encountered a problem like this, or have any idea how to fix it? i know it is a relatively old bey at this point, but i really like the way zeta performs in my stadium, and can’t find any solutions online.
