Weird behavior of my textarea with Medium Editors

I have exactly the same problem as Brad.

Odd Medium Editor Behaviour

I have Medium Editors on my site and they work fine. But for some reason below them there seems to be an HTML Preview textarea as well? This is only happening on one of my sites. Code: <textarea id="articleContent" name="articleContent" class="form-control" is="dmx-medium-editor" buttons="bold,italic,underline,anchor,quote,unorderedlist,justifyLeft,justifyCenter,justifyRight,justifyFull,removeFormat"></textarea> Screenshot: [23%20PM]

For me, bootstrap.min.css is loaded before dmxMediumEditor.css and dmxMediumEditor.js.
Nevertheless I have the problem.

Is there a solution here?

Check for errors in your browser dev tools console.

As far as I can see, I don’t get any errors.
or am I looking wrong?
