Hello, thanks for your answer, we made new support ticket via Shapedplugin.com. There you can see the url. Hopefully you can share this custom CSS what can make it 2 different columns.
But yes this is also possible when we create 2 different shortcodes, but here we face new issue you see, when we add shcema markup enebled in two different shordcodes and add them to the same page Google will shortly remind us that there can be only one FAQ Schema on one page, thats why its better to have only one shortcode what we can just but halve on desktop view.
