I tried "starring" OLH so that I could track my progress relative to my previous best time. TWICE I started up the climb and less than half a mile into it my Garmin said I was "off segment" and stopped giving me those data. Similarly, one time when I rode up Kings Mountain,. between Garmin and Strava, I was off the road most of the time, so it didn't find segments for half the climb - so, also not for the whole climb.
