Apple mail stuck showing one section only under "all inboxes"
On my iMac, few days ago I checked the flagged mail. Since then, when I go to All inboxes, all it shows me is flagged mail, although separately the other mail shows me individually what is in each one, but when I went back to click on All inboxes, it only shows me the flagged section. I have done a restart of my iMac and also did a total shut down and left the computer off for about 10 hours. No luck, it still happens. My iMac has every update on it. Updated to Ventura 13.5.2.
Thank you very much for your help if this is a solvable issue!
