Trying to Remove Box Appearing in Posts above "Tagged:"

[lizzzlu]

Hi there,
In one of the websites where we are using the "Agent Theme", there is a strange long rectangular box appearing over the line above where the tags are listed for each post and at the bottom of pages, too. The box is appearing in both the category-x and single-cat-x manifestations of the post and, again, I also see the box at the bottom of pages, but I'm not sure where to go to fix this.

Please see what I'm referring to by looking above the "tagged:" section in this post:

Please see what I'm referring to by looking in the bottom of the box above the "Property Details" section in this post:

Please see what I'm referring to by looking at the bottom of the page here:
http://thebarringtonbuzz.com/?page_id=2

Hopefully there is an easy way to remove this box on both posts and pages. Thank you very much for your help, Liz
