Dashed line on the Map
A dashed line on the map means that a route or track file, or a route loaded from the cloud is currently selected as a Map overlay
and thus, displayed accordingly.
To remove the overlay, go into the map overlay manager and select from the list what you want to hide (👁) or delete from the overlays (🗑). Your currently loaded route
is also displayed as an overlay with a dashed line and can be hidden in the overlay manager in the same way.
