Container bug

I’ve spent hours searching for the cause of a little bug that continues to appear while developing my site. If you go to https://www.realestateagentamy.com you can see in the AQ Page Builder container there is a tiny bit of HTML that SHOULD NOT be there. Right next to my text box there is a small ” ]” ” symbol, I cannot figure out where its coming from.

Has anyone else experienced this problem? Help would be greatly appreciated.
