Mail signatures disappeared
My mail program has stopped allowing signatures on my outgoing emails. There isn't an option on a draft email to choose a signature. The only choices are None and Edit Signatures. When I edit signatures in preferences, I see 6 signatures, but there is no option to click on one to be the default. How can I fix this? I'm using a 2020 Mac Mini with Monterey OS 12.6.
