OK
I know what you mean, but even the numbers I put in the upper third weren't displayed on any side of the rear wing, nor were the ones placed in the lower third.
The numbers placed in the middle third of the .bmp were used on the front wing, but not on the car's nose. In GP3Edit I chose them and also where to put them on the car, so that wasn't the problem, but they weren't displayed in GP3. Patching the .bmp and car number positions several times did not help. The only result was that I had a 11 12 number on the side of the car when I had put the numbers into the wrong area of the .bmp.
Ridiculous story.
