I have a rather small, but annoying and confusing problem.

I created a trapdoor and named it "Hidden Basemant", then I created a cell and made a nice basemant room with another trapdoor and connected the two via teleport. It all works fine, but the name displayed on the first trapdoor has changed to "Marker Storage Unit" when I try it out ingame. When I uncheck the Teleport box, it is again correctly displayed as "Hidden Basemant" as it was before I set the teleport.

In the CK, the name is also still displayed as "Hidden Basemant" when I select the item in the object window and click "edit". Does anybody know why this is happening? Any help would be appreciated. Thank you in advance!
