747-400FX texture problem when landing lights on

I have upgraded to the latest version, the only problem is when I turn on the landing lights for the cargo version of the base PMDG textures whether PW/GE/RR engine variant, I get a solid colour change to reflect the lights being on along the aircraft. It is vertical and it looks like the paint job was not a smooth blending. all other liveries downloaded are fine.anyone else seeing this ?
