Isotope Filter Not Working! Help!

Hi! I used the clone of http://dynamic-search.webflow.io/ isotope filtering. I copy and pasted the sections and put in my own content. I have been trying to get this to work for days and this is as close as I have gotten. The search works. And the All button works. But the categories do not work. Could someone please give this a second set of eyes for me to see whats wrong? Thanks in advance!
