Strange div layer showing up in email templates

[Anonymous]

Hello! 

This just started about a week ago. Whenever we edit a new email in a campaign, a strange div layer shows up: 

<div id="__DJI_CWE_SHORTCUTS" style="display: block; position: fixed; top: -5000px; left: -5000px;"><button>Alt+M</button><button>Alt+N</button></div>

It displays in the HTML version AND the text only version as Alt+MAlt+N.

Here's the best part: even when I go into the HTML Source Editor and delete it, it always shows back up again. Also interesting, it only shows up when you put in a token, link, or image. I've copied/pasted text only, and the div layer won't show up. 

Does anyone know how to remedy this problem?

I would check with support.

Were you able to delete it in the Template or in the email itself?
