We have more than 2 people having this issue. Myself included, but I’ve already live with it. It doesn’t always occur. I had to check and recheck all my AI traffic livery to have blank tail number and enable tail number to 0.
It’s usually appear with the white box if the AI traffic has the same livery that I’m using. But everything else doesn’t have it.
So I end up already ignoring it if I see it.
