I am not sure, if it is a,problem within MRA Next or an Here-Map-issue.
I have done acouple more "dry-runs" from different starting and ending locations and I haven't be able to reproduce the problem in for example the Sauerland area. Even when I have been in the Eifel today, I haven't ben able to reproduce the problem by selecting a locaton going south, but as soon as I tried to go back home, the problem was coming up consistantly, as long as I allowed the toll roads.
