I went back and checked, and the door's touching the floor.

I'm making a map in Ultimate Doom Builder for GZDoom, and every time I test the map the automap is way too aggressive, going so far as to show rooms on the other side of closed doors, including secrets behind fake walls. Am I making some sort of mistake somewhere? Do I need to be tagging secret sectors with something other than secret?

I want to enter. My goal will be completing one map, start to finish, with all difficulties implemented.
