Archive module not working correctly

Hello guys.

I have a new 4.7 installation. I have added the archive module, and then added some conent. It is back-dated from 2004 (because I'm moving my older site). When I look at the arhive model, at the calendar on the left-side-bar, it shows the dates where content is there in bold, and it's a link (i.e. it correctly sees that the content is there). When I click, it says "no posts".

I have made two pages in the current date (i.e. today), and they show up okay on the archive.

What am I missing?

Regards,

Ron.
