e mails marked as unread

Hi,

I am currently using an I phone 14 plus.

Every morning when I check my mail

box, I am shown that I have 2 unread e mails. I go into the correct e mail account, I then have to scroll all the way to the bottom (oldest), filter as unread, then delete.

I then go into settings, turn off the correct mail tab, re start my phone and the disappear.

The next morning, I have exactly the same problem with exactly the same two e mails.

Can anyone help please?
