Grid responsiveness on mobile version

Hi, I’m having issues with my grid responsiveness on mobile version portrait on my site’s Services section. On 479 px mobile viewport, it creates this unnecessary space at the bottom (I think it’s all the areas I added on grid on mobile version) and pushes the grid all the way to the top of my site. While it looks fine and responds well when scaling down to 478 px and below. I’d very much appreciate it if someone can help me resolve this issue. Thank you.
