It would be good that you first update your Toolset to it's latest version. Can you do this please?

⌥ You can use a plugin for this if you like.
I often use the Duplicator plugin for this purpose.
See: http://wordpress.org/plugins/duplicator/
I will need to disable all Plugins on that Site - that is why I asked a duplicator package to not mess on your DEV site.
Disabling Plugins can provoke data loss sometimes.
I also see you use Cache Software which by default must be disabled and cleaned to debug issues.
You also use a Child Theme, I would need to reproduce this issue with the parent Theme and no AddOn Plugins, as well no Cache Plugins.
Cache Plugins sometimes can not be simply disabled but need further action to be fully disabled.
Example for W3 Total Cache:
hidden link
Additionally i do not see the issue everywhere but only on WooCommerce Single Product Pages.
I edited this Layout:
hidden link
(hidden link)
I made the Cell and also the Row as test to be Full Width:
(see screenshot)
I saved it and reloaded the page, which now presents a full width Visual Editor Cell.
If this isn't working on other Layouts, most probably it's Custom HTML that interferes or a cache problem.
I would rather point to a issue with WooCommerce and WooCommerce Views, but for this I will need to fully disable all Plugins, have a clean cache and a parent Original theme.
Could this be possible on the DEV Site?
I rather suggest a Duplicator Package so I will not mess with your setups.
Please don't hesitate to inform me in case the issue persists
Thank you for your patience.
