[Enigmail] i use only GNUpg & Enigmail - But, i can't send Msg without certificate ?!

Sorry for Language Mix! ;-)

I use Thunderbird (60.7.2) on Debianoid Distri
I use Enigmail Version 2.0.8 (20181029-0441)
(It comes whit TB Pakets)

After a fresh Setup from OS, TB and so on, i import my Backup (.gnupg)

I write a new Msg, "autosave" and/or Send Button tells me:
> Senden der Nachricht fehlgeschlagen. Sie haben ausgewählt, diese
> Nachricht digital zu unterschreiben, aber die Anwendung konnte das
> Unterschriftszertifikat nicht finden, das Sie in Ihren
> Konten-Einstellungen angegeben haben, oder das Zertifikat ist
> abgelaufen.

That's Bullshit!: "You have chosen to digitally sign this message"

I never "chose" such a thing!

Engl. Translation:
> Sending the message failed. You have chosen to digitally sign this 
> message, but the application could not find the signing certificate 
> you specified in your account settings, or the certificate has 
> expired.

In the GER Thunderbird Forum i was found something to CERT.?! I don't
use any "Cert" for my GNUpg/Enigmail

What do I have to do to be able to use Enigmail again and exclusively?

Thanks
Michael
