I hope you are well today and thank you for your question.
I have tested it on my test site and it’s working fine for me using latest version of Gillion theme as displayed in the attached screenshot.
Please make sure that you are using the latest version of Gillion theme and page builder plugin.
This can be due to plugin conflict on your site so please try temporary deactivating all plugins except Unyson plugin and WpBakery page builder plugins and see whether everything works fine and then enable the plugins one by one to see which plugin is conflicting if any.
Would you mind if I log in to your site and do some troubleshooting? If this is ok then could you please temporary share me your site admin log in details privately by adding them in the box having text “Enter your private content here (only you and forum moderators will be able see it)”?
You are using the plugin bundled with the theme therefore you are not direct customer of that plugin and cannot update that plugin until you purchase it.
Please find more information about it on the following page.
We update the plugin with every new theme version. In this case you can just delete old plugin version and reinstall latest plugin version bundled with theme from Appearance -> Install Plugins
