Light problem

So i managed to merge the POSKY-PMDG 747-400 with good results, but there is just one thing that bothers me. At night, when you turn on the DOME light, there is a light cast on the front fuselage of the plane (see image). This has nothing to do with the [light] section (i deleted the whole section but this problem remained).Any ideas how to get rid of it? Is it a PMDG problem? And dont repsond by saying things like "you can't merge the POSKY-PMDG" and "why did you merge the aircraft, the PMDG model is fine" etc.Thanks,Boeingsta.
