Pay with Like Facebook Comment Window Not Showing Correctly

Hello! I installed the pay with a like plug in, set it up, and most everything works at expected, I believe. However, I enabled the facebook comment box and the pop up does not appear in it's entirety. It gets cut off by the next post in my archive. See attached screenshot. Not quite sure what to do.

P.S. Would be super nice if this plug in had a Share feature instead of a like. Many times facebook / google "likes" don't show in user's feed from what I can tell.
