MacBook Pro (13-inch, 2020, Four Thunderbolt 3 ports), Monterey 12.3.1. When I click on a mail message, it displays the body of a completely different email. Tried rebuilding the mailbox but no change. This doesn't happen consistently, which makes it more annoying.

Note—
• IMAP accounts stay on the server, so no local loss, when you re-sync
• POP accounts download and remove from the server—therefor save your inbox/sent box if you want them
• "On My Mac" is just that, local folders you created and moved mail into. So no loss
