Engineer can build in the func_respawnroom boundaries, but the only buildings he can build are teleporters?

[RufusFluffy]

So I was following Crash's mapping tutorial, not to the letter, but close enough so that everything should've still been working on the mechanical side. However (for whatever reason) Engineers can build teleporters in the rooms for some reason? All my resources say it should act like a func_nobuild but it just.. doesn't? I'm new to talking on forums so if there's anything missing let me know and I'll try and provide it.

if the trigger isn't touching the floor there's a chance you left just enough room for teles to fit underneath the trigger
if that's not the case though...unsure what the cause would be then

Engineer can build in the func_respawnroom boundaries

Engineers can build in the boundaries because of source spaghetti, the right way to do it is add a small func_nobuild in the exits so engineers can't actually place teleporters clipping into the doors, for example, Powerhouse does it like this

I don't mess with spawnroom brushes enough, but (like Mâché said) is it fully encompassing the room? does it have the team keyvalue set to the actual team? I doubt the second one is the issue but with the Source engine it could be.
