A random grey box appears in the middle of the content editor, sometimes. I've seen it on all browsers. Has anyone else had this happen? Running Q2 2016, Learn 2016 theme. The box does not appear when published.
Strangely enough, though, Blackboard strips the paragraph space right underneath Weeks 5 & 6. It doesn't strip the space when it is above the grey box. However, my colleague pasted this content from Word, so it's possible the grey box has nothing to do with the formatting of content.
