Poppy e cancel glitch

Hi guys. So, every time I try to cancel my E as poppy, it sometimes doesn't cancel. It happens even after 2 seconds of canceling the command. It's really annoying since it can make me go suicide at times. This issue occurs almost every game, although it isn't completely game breaking, it can be. Sincerely, a poppy jungle main. edit: I use the lolipoppy skin currently
