Categories not appearing

[friendsofthefletcherfreelibrary]

I just opened a basic Store and followed the directions to add a number of categories in the "Edit My Store" page. I have placed several books in some categories. However, the categories do not show up in our Store. What might I be doing wrong? Thanks for your help. Stay safe and healthy

Here is a link to our store.

If it's a new store, it could take a little bit for everything to update.
