Grid shows multiple empty cells

Im not sure whats going on

Its messing up the footer layout and i cant get rid of them

Here is my site Read-Only: Webflow - Heyer & Associates Website
(how to share your site Read-Only link)

ends up looking like this

Your last item in the grid is manually positioned in mobile view to columns 13-16, change that and it should fix it.

Thank you so much…i spent entirely too long not understanding what was wrong.
