Trails showing on map on watch but not on connect / online maps

G'day,

The map on my watch shows trails (red dotted lines) but they don't appear in garmin connect, see the picures. If I make a new course in connect it knows the trails are there and plots the course along the trails even though they are not visible. Is there a way to view these trails on connect or is there a way to view online/download the same maps that are on my watch. These are old MTB tracks that I would like to explore but they are over grown in areas and it would be easier to follow using a larger map on my phone than the one on my watch.

Cheers.
