Go to the [fltsim.x] sections and make sure the 'title=' entry is unique for each variation.
[fltsim.1]
title=Boeing 737-800 Paint2 <----must be unique amongst ALL aircraft in the sim
..............
ui_manufacturer="Boeing"
ui_type="737-800"
ui_variation="World Travel Airlines" <---should be unique within this aircraft
......
Do not change any 'title=' entry for the default paint variations as this is the data looked for by the default ai traffic file. If it cannot find that entry that aircraft will go missing from the ai......or......to add to the confusion...

While your in there you could 'trick' the ai traffic file into using one of your real world paints by copying a default 'title=' entry to a real world paint. As an example:
Say you have a United Airlines paint in [fltsim.8]..copy Boeing 737-800 Paint2 from the above [fltsim.1] to [fltsim.8]...
[fltsim.8]
title=Boeing 737-800 Paint2
......
...then edit the entry in [fltsim.1]
[fltsim.1]
title=MS Boeing 737-800 Paint2 <---just an example for the edit, can be anything.....
Your United Airlines will now fly as ai in place of World Travel Airlines.
Of course, if you have already customized ai traffic this isn't necessary...
Always backup any file before editing.........
