Lights not showing in the sim

[scubajuan_new]

Hi, 
 
I converted a scenery of MUCC (Cayo Coco, Cuba) and the first thing I wanted to do was to replace the apron lights with HDR lights. I placed 4 AreaFloodHighMast.obj from \lib\g10\streetlighs, but for some strange reason only one of them shows up in the sim. I can see all 4 in Overlay Editor and in WED as well, but not in the sim.
 
I am using WED 1.2 and X-Plane 10.20rc1 on a Mac with OSX 10.8.2
 
The Scenery I am converting is not freeware therefore I am attaching only the apt.dat and the BGL with the newly placed lights (no orthos or other objects) but even like this those lights don't show up. I also removed all other sceneries for the custom scenery folder in case there was some other pack conflicting with this one but no luck.
 
Any ideas?
