FS9 MD-11......"MF PMDG BG"

In FS9 my MD-11 shows the letters "MF PMDG BG" above the cockpit window in spot view. I have done a repaint for our VA using the painkit and with the passenger version these letters have not shown up, which is good..........but in the cargo version they show up on my repainted livery, which is not good!I have done a thorough search through all the files for both the PMDG livery and my new repaint but I cannot find these letters on any of them so I am unable to delete them.I assume they are supposed to be there on the original PMDG house livery but can you please tell me how I can remove them from my repainted livery?Many thanks.John :(
