funcdoor acting weird?!?

Ok, I'm making a door for my resupply room. Note that I have allready done resupply doors that were working correctly. Well, this time, it seems like it wants to challenge me .

Anhyway, I'm making my func door, changing settings, clicking apply. Then, I'm trying to link my door with my funcdoor, what happens? funcdoor is funcdetails. I try again, same thing. When I un-select my funcdoor, it changes to a funcdetail.

I tried importing a door from Goldrush, not working, I tried different textures, not working.

Is there a setting I might have clicked that makes it impossible to change brushes functions? Cause it's not working for any other fonctions...

Thanks for your help!

Well, thanks a lot mate!
