It seems there are several issues with using Confluence with Microsoft Edge. We currently use the cloud version of Confluence and JIRA and we see things that don't work properly in Edge however if we use FireFox or I.E. then it works fine.
Our fix is to just tell everyone to stop using Edge but I wanted to make you aware that we have seen things not being displayed properly in Edge but with the other browsers it works fine.
fyi.. We are using Edge version: 38.14393.2068.0
