Understanding Flex Loop Filters

Hello! Kelsey here from BluedotLiving.com. We are hoping to create better filtering options for the recipes on our Food page. I am looking into the Flex Loop and Flex Loop Filters on our staging site, but I can’t seem to get them to display properly.

I would like the block to show only the recipes category, and then be filterable by certain tags (i.e. dinner, breakfast, fish, etc.)

So far, I can only get the full list of categories to display, and rather than filter they link to the category page. How can I make the block filter by tag?

Thanks!
