So basically, this medium distance line (purple big line in the second photo) is taking away points from my map, which I do not understand because:

1. This line is in real life and is used a lot, connecting two major metropolitan areas in the region (Andalusia)

2. Other maps have the same line I have made and actually gain points from it.

So I don't get it, why is it taking points from me? Will other medium distance lines take away points too? I have tried to make the one to Jaen and it took away a lot of points.
