Credit being added to FB share description

Hi, I have another quick question. We noticed when people share a post on Facebook from the “Share this” option, the image credit is showing itself in the meta property=”og:description” field and we need to hide that. We only want the credit to show up in the post but not take over the Facebook description. It seems to place itself before any other description meta info.

Is there a way to disable it from showing up in that meta property=”og:description” area?

Thank you in advance!
