Featured image and some details Help?

Hello again,
On the last question you were very helpful. But there are still some issues.

1. I am adding [eab_archive lookahead="yes" weeks="52"] to a post and only one event shows up. So I don't know how to proceed. Tried to delete old events and add new ones but they too do not show.

2. On the eab_archive items we would like there to be some description added under the title of the event.

3. And on both single event showing or event archive the featured image (added from the administrator panel) is not showing.
