Hi there,
Thank you for providing the details.
I’ve checked the site and as Leo recommended, it’s best to start using the containers block in GenerateBlocks instead of Sections as it’s an outdated module and will no longer receive updates.
The best solution for the section w/ the issue is to change the HTML structure of its content to make it display properly. You’ll have to write the HTML code in a way where the section will display a column layout.
This is quite tedious to do, hence, we recommend GenerateBlocks Container and Grid Blocks over Sections module.
