Vatsim vpilot model matching for 3rd party

Currently if using vatsim and vpilot the display is quite impressive if you create your own VMR file. What happens however many have found is that any 3rd party aircraft that are not featured in the market place I.e the pmp a330 will show up as the first loaded in livery rather than the correct one, basically put if you came across a British airways a330 first it would then show up as British airways for all subsequent a330s regardless of airline.

This only affects 3rd party aircraft that are not in the market place, the crj and a32nx work fine. So surely there is a way this can be fixed
