Tablet view on front end not working

Hi there. 

I have the following issue. On my front page, on my books section page, and on my video section page the tablet design is not working. I have designed all pages with Elementor, and in the editor the tablet mode design works fine (2 columns for tablet), only on the front end it doesn’t. Instead it shows one long streched column.

Here is a screenshot of the issue:

I am using Ocean WordPress theme, but I also tried a WordPress default theme (twenty twenty four) with the same result. I have tried disabling all plugins, and non of them seem to be responsible for the issue.

P.S.: I haven’t yet had any opportunity to check whether it looks like that on other Tablets also.?

The books section page is?https://highermindart.info/books?, where on tablet is should basically show the desktop version (book cover and text side-by-side). The video section page is https://highermindart.info/videos/ . Any help would be great.
