Objects not showing up in FO3 gameplay?

[Ricochet84]

Hi, I'm pretty new to the G.E.C.K., so this might be a simple question.

 

I tried editing the interior of Jocko's Pop Stop, but somehow when I duplicated the ID, I ended up with three separate veriosns: "JockosPopStop *", "GasStation2 * D", and "zGasStation02 * D". (Those are all the EditorIDs. The names are all the same.) "JockosPopStop *" has all the objects I want. "GasStation2 * D" is empty. And "zGasStation02 * D" has just a WoodShackDoor.

I saved the .esp file in the Data folder and selected it in the Data Files part of the Launcher. When I run FO3, and enter Jocko's Pop Stop, I enter an empty room. All that is there is the door. So it appears that "zGasStation02 * D" is the one that opens. Is there any way I can fix this so the right one opens up when I play?

Thanks in advance.
