I unstarred a Strava segment and deleted it from my device but every time it syncs it reappears on the Garmin. Checked on Strava and it is not listed under my starred segments. Does anyone know how to fix this and stop it coming back?
Check that you don't have a goal set for that segment. That will also cause it to reappear. Happened to me.
I had starred and set a goal time on a number of segments. I unstarred a couple of segments but they kept reappearing. It wasn't until I realised I had a goal set as well that I had to remove the goal for the segment not to show up on my device.
Any segment you star or set a goal on will be automatically synced.
