Google maps not working when hummingbird is activated

Hi there, I seemed to be having success with your hummingbird plugin however I noticed my google maps vanished from the two pages they were displayed on. I am using latest version of wordpress and latest version of a theme called Avada.

I reverted everything back to how it was in hummingbird and the maps were still not showing, I thought I would try disabling the plugin and the maps came straight back.

Is this something you have come across before and is there a way to resolve it please as i would very much like to use the hummingbird plugin on this small but slow website.

Thanks.
