I just updated to 115.8.0. I have a much older mac without the upgrade and it is not having the same problem as my os 12.6.3 mac. Some of my inbound emails from are being taken over by a particular email from another sender so the message displays as the other sender, as does the from and reply to, but the subject retains the info from the original sender. Three or four emails in a row will all look like the other sender. The other sender was a public radio station. What's going on?

For example, the email displayed below is from one of my vendors, and has a simple message saying Thanks. The subjct line referencing a quote is correct. The rest is not.
