Workouts not remembered by Zwift - help!

Not sure if this is the right placed for this topic…

I completed my first race today plus a cool down in another world (yay go me) however the program seemed to crash on exit (MAC) and hasn’t been recognised in Zwift towards XP or in the Zwift companion app. I have the .fit file and have the data in Strava, is there any way to upload this back in to Zwift so my stats and data are correct?

Cheers, David
