Corps – Pages not loading properly (Sidebar issue?)

Hi

I have noticed that on both by Corp sites, one is to launch shortly, so neither on public view. Pages don’t load properly. Content is momentarily squeezed onto the right before settling as it should

I also noticed that on one full sidebar of widgets appeared from nowhere, there is nowhere to turn it off in Corps, so I had to go through and remove each widget (Twice)

The loading issue has just started just as I want to go live, now I am hesitant due to this issue.

Any advice?
Thanks
Roland
