Lights bleeding through walls into neighboring rooms

[DBees]

So, in my dojo we decided to make a sort of floor dedicated as an apartment complex for the members to do whatever they like with their own rooms.  However, rooms with different lighting colors will bleed into the ones built right next to them.  I've tried adding the decoration walls on both sides of the rooms to hopefully block it out, but with mixed results.  Note how, the one side manages to block 90%of the light, while the other side doesn't in the slightest.  https://imgur.com/a/SDemhPe

Interestingly enough, the bleeding light disappears the moment the door to the room with blue lighting opens:

Is there any chance this can get looked into and maybe fixed when the sacrifice and tennocon settles down?  Otherwise, I'd hate to have to restructure the whole floor (and redcorate my rooms) over what's plainly a visual glitch.
