Failed to sign email. Thunderbird or enigmail bug?

Im running buster (testing) and im trying to send signed email. My keys
are on my yubikey.

I get the following error message

"Sending of the message failed.
You specified that this message should be digitally signed, but the
application either failed to find the signing certificate specified in
your Mail & Newsgroup Account Settings, or the certificate has expired."

If i press encryption button twice (encryption on encryption off) the
problem is solved.

Any ideas how to solve it?

I want to report it as a bug. How should i report it as a thunderbird or
enigmail bug?

Thanks for your help.
