Players change animation to swimming one when close doors right in them

As I already said, players just swimming whenever they collide or stand at the same place with an open door then close it (real problem here is closing door when players stand right inside it). It feel really weird cuz there's literally no water there and they keep changing animation (swimming one when the door closing, and back to normal when open it).
