Ahhh glad to hear you were able to confirm, I know you said it worked correctly for some other services but thought it best to double check.
I was able to locate a similar issue related from another user’s post here.
Consensus here would be to contact Bitwarden support directly for technical support as this would most likely be a backend issue that they will need to help resolve.
Let us know how it goes and if it gets taken care of, would be interested to know as it appears to have come up for some users occasionally.
