Grid not loading properly on Mobile


I have a section with a grid that doesn’t load properly on mobile. When I open the page and scroll down, I only get 1/4 of the grid to load. Images are attached for reference. It’s only when I scroll past the grid, does it load properly.

Could someone help me troubleshoot the problem?
