Word Markups Automatically Turned Off

I am using Endnote X7.6 with Word for Mac 15.25. Every time I add or remove a citation while I am working on a document, markups suddenly go from show “All Markups” to  “No Markups” regardless of whether CWYW is on. I then have to manually switch back to show all markups. Can anyone explain how to prevent that from happening?
