It looks like a problem that started in January and is partially fixed but obviously still impacting some racers where their fit files werent being processed at the conclusion of the race.
I would send an email to zwiftpower@zwift.com and request that they fix up missing results and suggest you mention your training partner’s ID as well as the event ID.
The below thread is where Zwift were asking people for events that needing fixing due to this problem (and they would process requests once problem addressed) but when I just spot-checked some of the peoples missing data, they are still not corrected - this may be a sign not to get hopes up!
It may pay to reference the below thread in your email too.
