Strange code keep appearing in Armadillo blog

So every once in a while I come across this code my Armadillo blog:

span id=“selection-marker-1” class=“redactor-selection-marker”

I tried to paste the hole code but the forum software doesn’t alow it. But the span comes with the < & > brackets and the close span as well.

Think I just answered my own question. By giving the div this span attached itself to a nme the problem went away, otherwise, just editing it out of the code made no difference, after publishing it just came back.
