bus license plate

Please help me remove the license plate overlay. I made my license plate on the bus, when I enter the regular game (without the bus company addon), then the license plate is displayed the one that I made, when I enter the game through the bus company addon, the bus company superimposes its license plate on top of mine. Although when buying a bus in the license plate section, I removed everything and left this field empty (attached a screenshot). how do i fix this so that the license plate doesn't overlap on top of mine?
