Underwing N Number Livery Issues

Please remove if this is in the wrong section. I’m having an issue with the Citation CJ4 that is driving me crazy. Every single livery that I have downloaded that doesn’t have an underwing number, including the default ones show the tail number on the wing. I have tried editing the config files in the official folder as well as the liveries that I have downloaded. Nothing seems to work. Any help would be appreciated.
