Show certain items in category with filter

I am having trouble showing certain items on a page using a collection list and filters. I am able to show each button for the category, but I want only the items in that category to show when the button is pushed. (or all of them to show when “show all” is pushed). Each time I make the change for one category, it changes all of them to be the same.
Categories: All Items, Geogrids for Subgrades, Geosynthetics for Subgrades

Thank you.
