TDZ stage 6 and 7 not counting toward completion

Hi,

I completed Stage 6 of TDZ 2021 on 02/02/2021. The activity has been saved as 02/02/2021 in my zwift feed. I cannot open it and Stage 6 is shown as not completed in my zwift account.

Same thing happened with Stage 7. I completed stage 7 on 02/05/2021. The activity shows as 02/05/2021 in my zwift feed. I cannot open it and Stage 7 is shown as not completed in my zwift account.

At first, I was going to re-do stage 6 at the end of the event. But now, re-doing two stage is not something I am looking forward.

I run last version of zwift on windows 10. I run the companion app on my android phone. My trainer is a wahoo kickr 2018.

Not sure what I should do now
