thunderbird 115 all emails show on startup but I'm set to view only unread

Just upgraded to 115 Supernova and all seems great except for one feature. In the past, by default, I always set my "view" to unread messages only. I'd go to "all" if I needed to. Now in 115, I set the View setting to unread, and that works during the session. However, if I shut down Thunderbird, or restart my computer, 115 defaults to show All emails. This is a bit frustrating to have that extra step to go to the toolbar and switch to view unread emails when I startup. Any suggestions to fix this? Thanks in advance.
