How to remove the "Most Used Terms" block

I would like to remove the "Most Used Terms" block in the right side column on the front page. I went to Context and disabled the Most used term block in the section "openpublish-listing_pages-frontpage". But when I went back to the front page of my site the left column was gone (list of articles) in addition to the terms block on the right side. When I reverted it back to default everything returned to normal.

Any thoughts? Thank you for your help.
