create landing page with nibble builder

Hi! i tried to create a simple landing page with this plugin. I would like to create a page with two-column sections. Simply the image on the left and the paragraph of text on the right. Then below the paragraph of text on the left and the image on the right. All good in desktop view. When the same page is viewed in mobile I don’t find the alternate contents like this:
Image
Text
Image
Text

Instead I find the content in mobile like this:
Image
Text
Text
Image

How is it possible to make it in alternating mode even in mobile. In the official plugin page I see that it works fine.
