I don't understand what you mean when you say "just check the panel.cfg that is working." There's only one panel.cfg file, and it works for one livery.
Since I don't think you quite get what I'm saying, let me elaborate:
The VRS SuperBug comes with over 40 different texture sets (liveries). They all use the same model and panel, so there's one universal panel.cfg file that applies to every single texture set. There is only a single aircraft.cfg file as well. I have many add-on aircraft that use this exact same organizational method (i.e. one model, one panel, many different texture sets). Even though the indexer and the panel utility break every aircraft down into type (i.e. P-51, C172, etc.)., the Aircraft Type Name Editor only picks up on whatever is the first entry in each aircraft.cfg file, and when I get into FSX only that first aircraft works with VoxATC.
This problem is not isolated to the VRS SuperBug, it is true for every aircraft I have with multiple texture sets/liveries. If it is an easily solved issue, please tell me how to do it - I really want to use this program with all of my aircraft.
