Grid not loading

I have a few grid, two on my home page and one under the “step outside your border” page. Although my first two-column grid shows up on the homepage, the one under, and the one on the other page, goes not show up when I load the page. It is only when I refresh the page that I get the grids to show up.

In addition, the grid seems to overlap my footer before it adjusts itself.

Thank you!!
