Today I did a ride with a Strava Live segment. For some reason the 530 put the same segment back-to-back, doubling the distance. The profile also showed the elevation resetting to the starting elevation at the end of the real segment.
I was also recording this on my 935 which did the segment correctly.
If Garmin wants to check this, this is the segment:
