Undiscovered ETS2 Roads (Transparent GPS Line) - Road traveled still in red

[Leo Felix]

Hello, everyone. I don't know if anyone could help me, or if it could even be a bug in the mod, but I'm in Montenegro, on a bridge located southwest of the city of Bijelo Polje, and a part of this bridge simply doesn't show as covered. It stays red the whole time. I've crossed it going back and forth and nothing. It doesn't go away.
I tried to post screenshots to help, but either it's not allowed or I don't know how to do it, sorry. I wanted to know if it's some kind of bug, if the section will count towards the map, since I'm trying to get 100%, and if there's any way to get around it. And this isn't the only section. I've found others that refuse to be marked as completed.
Does anyone know what might be happening?
I appreciate the help.
