Kalista Bugs

Hi, Im here to report some Kalista bugs that I have stumbled upon while playing her. Firstly to her E. We all know that when you kill something with your E, it resets, but apperently sometimes it bugs and it doesnt reset...it happens mainly when you are in a big enemy minion wave and you have a hurricane to stack your E to multiple targets and when it clearly looks that the minions are dead from your E, it doesnt reset...this is the biggest problem in the world but it has happened to me when im in a scurmish scenario or in a tf and I kill an enemy champion with my E but it doesnt reset and i fail to kill more targets...Anyhow, there is another bug with her ult, when you pull your binded target and he shoots himself in a location, sometimes he gets knocbacked slithly in a buggy way backwards. Thanks for your time!
