Feedback stacking and loading before full page load

I recently noticed on our WordPress Canvas site that our feedback (testimonials) drops down when pages load. It never used to happen and i assume it started with an update but am not sure.

This happens on all pages and i have absolutely no idea how to fix it…
We don’t use any third party plugins for the testimonials, simply the Woothemes Canvas default plugin.

I have tried:
Disabling the plugin and using third party ones. This didn’t work and would still drop down with the site load so have now reverted back to how it was originally.

Loading the default themes that are installed within the site –
Twenty Eleven
Twenty Twelve
Twenty Thirteen
Twenty Fourteen
– they all have the same problem.

The site, plugins and framework is all up to date.

I have today also clean up all plugins that are not necessary and now have a mere eight installed on the site….

I don’t pretend to know what i am doing and definitely need some help 🙂
Thank you in advance!
