@contact-miracleozule hey, unfortunately, without the screenshot or video we won’t be able to tell what exactly is happening with the mobile breakpoint of the site you are working with
but at the same time, in case that the issue is like the initial post got, such behavior could occur due to the layout change from desktop (wide screen) to mobile (vertical screen)
So, the content got to be re-adjusted according to the screen ratio.
Along with this, please note that you can use different grids for different breakpoints, which could help you to deal with such behavior. So, for example, 3x1 grid can got 1x3.
