This bug has been present for a while (maybe already in version 1.10.x) but I have only noticed it at low zoom levels <= 10, which I seldom use. The problem isn't that Locus is showing the red lines but that Locus draws the red lines between wrong coordinates. Maybe it is related to the POI-grouping algorithm as I have only noticed it when I enable POI-grouping.
As you can see in my first image Locus draw the red lines like it is 10km and more between a waypoint and the geocache it belongs to. This is almost never the case in real life. The red lines also seems to converge into different points.
I hope this can help you to solve this bug. Below are my example images.
Zoom level 10 with POI grouping enabled - Locus draws lines all over the place as if the waypoints is many km:s from their geocaches:
Exactly the same position on the map but with POI grouping turned off - the lines go back to normal:
At zoom level 11 all seems normal, both with or without POI grouping:
