Bitlocker asks for recovery key after A25 BIOS update on Dell Optiplex 9020

Today I ran an unttended BIOS update to version A25 via command line on multiple Optiplex 9020 with enabled Bitlocker. After the update all Dells were stuck at boot asking for the 48 digit Bitlocker recovery keys which was a pain to enter individually. After entering the keys I also had to log in to each Windows to make the Dells boot without having to enter the recovery keys again.

Is this somehow expected or is it just another bug?

Here I see a list of devices affected but I don't see any Optiplex there:

Thanks in advance,
