It appears after compilation that additional line data (looks like tile grid) is generated by cGPSmapper and causing visual conflict with actual line data.
It is all straight lines running through the map. Some of it is fragmented, some of it is continuous.
Most if it has labels like "This map has been made with cGPSmapper" or a contour elevation number label or a county border label. It is totally out of place but I have no idea how to edit this.
Can someone offer some ideas?
