I have a serious issue; I have grass from one World Space showing up in both other world spaces and in-game. I have looked around for a fix, but to no avail. Do you think there's a solution to this?

Basically whenever I go in-game and I type "coc WorldSpace03" and then I go to WorldSpace02, in WorldSpace02 I see grass floating close. However, if I go to WorldSpace02 before hand there's no such problem. (The problem also happens in the Creation Kit, whenever I go to WorldSpace03 and then to WorldSpace02 I still see the same problem I can see in-game)
