[Creation Kit] Tiles continue rendering outside of a room

[Vortex Lord]

So certain tiles despite being in a room persist in rendering despite me being outside of their respective rooms.

 

Spoiler

 

I'd love to know what causes this and how to fix this. Are my rooms and portals bad or is it something else?

 

Edit:
I meant to post this in the Special Edition section.
