I've had that happen with PM's during sprint obvservation training with someone using an SRM - my Garmin just dumped my PM in favour of theirs. I didn't notice until the end of the session, when I'd done two more 200m efforts. Dick.
The issues with my track PT turned out to be a Garmin issue - resolved by pairing with two head units and comparing data, then factory reset of my Garmin. S
