mail changing 'sent from' account

Since Ventura. Sometimes when I compose a new email, Mail defaults to my gmail account which I rarely use. The 'send from' drop down menu doesn't show any other accounts. I have to quit and re open mail and the 'send from' still shows my gmail account but the dropdown menu then shows my other accounts and I can then select my .mac account. In Mail settings my .mac account is and has always been set as the default 'send from' account. Anyone else having this problem?

Thanks, Tom
