Please download an archive of WPBakery 6.10.0 by link from the Private content area and test it.
If the problem persist, check how it works when a default WP theme activated (not XStore), for example – Storefront theme.
It is important to check if the problem persists with the default theme to find out if it comes from the theme or from something else. Go to Appearance > Themes > install and activate the Storefront theme. Then test and let us know the result.
Widgets could be messed up after switching, so open the Appearance > Widgets tab before switching to be able to move the widgets to the correct area after switching back.
