Doors from a duplicated cell won't show up

[kingtitan]

Here is my problem. I duplicated one of the cells from the Carnecerous prison mod (cell block a) to add to another mod I have. Most everything works fine (i got the "teleport" doors and references working fine), however, when i go into this duplicated cell, all the doors in it are missing (minus of course the "teleport door"). These are the type of doors that have animated swinging (they dont take you to another cell) but for some reason they don't show up. I can see the doors in the render window within the construction set which is confusing me even more. Any suggestions to fix this?

 

EDIT: Fixed the problem. Doors shared identical id's with doors from other mod, hence the "invisibility"
