How to change All Products page description text

I successfully replaced the collections/all page with my own, so I could update the title. The previous description, which has errors, is still showing up, although I fixed it in my new collections/all page description field. Why is the description of my new collections/all page not replacing the old one? Where can I change the source of the description for that page?

This isn’t clear. I have the description field populated with what I want, but the live site isn’t updating.
