Why is there a 2. Route line

The White line is the original route

Jörgen,

I'll see this line also and in my case it was a straight line between plot points that make me confusing while driving (not curvy one like yours)

Finally I deactivate "Show tracklog line", even that I'll be not tracking this route, and "second line" dissapears.

I do not try to activate to see if it appears again.

Perhaps is the same to you?

Regards

It's indeed the original route as @Marinus-van-Deudekom said.
You can disable it by deactivating "show original route".

Ideal to orientate yourself when you drive some offroad sections / deviate from your route due to road works etc. Then you know where you should have been driving.
