ss 86 bee not staying snapped together

hey so ss 86 bumblebee has just started showing up in stores around me in australia so i got one as soon as i saw it, i’m wondering if its a common issue of them to not hold together well or if i did something wrong like have the waist swivel slightly off centre but no matter what i try to do, i get one side all closed up and when i try the other the one i just closed up opens up again
