i can do kill @e[type=!player,type=!villager] to kill every entity except me and the villagers, if you meant this (kill @e[type="your entity"])and everything got killed, this is a bug.
btw this attachments 10mb limit is so annoying, i got a video about a size of 10.3 mb and it didnt accept it. now i need to make it 480p.
