Hi Erin,
I'm not terribly familiar with this app, however I suspect that the app is doing some brute query to pull a bunch of data from the API and then filtering them out on the front end based on criteria that is in the selectors. I've seen a couple of other apps do that, where they report some high number of results but only shows 3 things in the list.
What is the difference between the two screenshots you're showing above? Different projects? If I remember correctly, that can be explicitly defined in the config settings of the app.
