When I log in in the morning, the number of unread message in a

Just out of curiosity, what is happening here?

You are most likely set to download x00 messages at a time rather than all
messages, and to download NEW headers. As a result, OE only downloads new
headers, not the older but still unread ones.

You can either click Catch-Up to remove them all, or, after you've marked an
All Read, leave the group, come back to it, and click Headers in the top
menu; that will download older headers.

Or, remove the restrictions on download New Headers only. It's all in the
Tools, Options.
