No intensity minutes for activity

Hello everybody, I got an edge 840 and after today's workout (indoor zwift session) there were no intensity minutes count showing on the activity report. 

At first, I thought it was because of the 24.19 update, but it seems like my last workout was already on 24.19 and intensity minutes were working correctly.

Everything else is correctly sync with connect, training effect, active calories, recovery time etc... worth noting that my activity HR is missing on the daily HR glance while it's tracked and recorded correctly on the activity summary.
