Activity appears in the future

February 7th I did a workout (4wk ftp booster wk1 day 5) around 20:30 CET.
It does not show in my Zwift-activities and did not appear in Strava and Garmin Connect
But it appears in my Veloviewer at February 14th!
As I cannot find it in Swift, I cannot find an ID for it.
Is there a way to see it?
