Event not listed in my profile

Hello zwifters,
Yesterday I participated in a 90 min / 50km ride in France (Ascenders Team Social Thursday Ride). The activity is listed on Zwift profile, but does not appear in Zwiftpower. Not a big deal (just another group ride), but strange. My HRM was not correctly working (capped at 96 bpm), could this be the reason?
The activity was also transferred to Strava and appears as always.
