That is for sure an old pass cover. It's from 2020 or older. On the back side, in the middle on the right side next to a 1-dimensional barcode, it will say from which year, e.g. "2019 Edition”.
I'm afraid this is an issuing error by SNCF. I'd report this to customer service and ask them what to do.
You could also go back to the sales point and request a 2022 pass cover.
