Completed Zwift Academy workout, started another custom one afterwards via 'menu' - ZA w/o shows no completion

it looks like you are not alone, this sounds similar

No credit Zwift Academy 2023 Stage 2

I am missing the 2nd workout credit. I performed the “Fatigue fighter” workout (shorter version) during a standalone ride but no credit for the completion (full stars). What’s wrong with that? I’d like to receive the credit.
