Problem with Tail Number Registration

[VisualRules]

@Flight Numbers being censored. Why?

Since the sim came out I have used flight number 308 (the number has significance to me). All of a sudden, ATC stopped saying it, so I checked under Customization and the flight number was *** . Changing it to 308 and pressing enter makes it blank out. I can successfully use other 3 digit numbers and 308 works if I add a number before or after it (4308, 3085, etc.) Can someone else try 308 and tell me your results please? I can’t imagine why 308 is a naughty number.

Hello,

Thanks for your response. My problem is that in the registration field where you can customize the number you enter, it is empty.

So it can’t be some inappropriate name that I’ve put because I’m not putting any. I just want the white stripe to disappear from my fuselage.

I’m suspecting that it could be some of my aircraft installed at MSFS

I am checking.
