In Foundry Contour, How do I filter by multiple terms?

Background

I'm working on one of the tutorial exercises "Bootcamp, Day 1"

---

The Problem

Specifically, the problem says

Filter this Flights path to only: Flights between Delta Airlines hubs (ATL, JFK, LGA, BOS, DTW, MSP, SLC, SEA, LAX)

I know in SQL I would do something like:

SELECT * FROM flights 
WHERE origin IN ATL, JFK, LGA, BOS, DTW, MSP, SLC, SEA, LAX
AND dest IN ATL, JFK, LGA, BOS, DTW, MSP, SLC, SEA, LAX

But I'm not sure how to accomplish this in Contour. I know I shouldn't have to put a new filter in for each airport and origin/dest, right?

Question

How do I filter by multiple terms in one line?

What I'm Looking for

I'd like to do something like

origin is in ATL, JFK, LGA, BOS, DTW, MSP, SLC, SEA, LAX

AND

dest is in ATL, JFK, LGA, BOS, DTW, MSP, SLC, SEA, LAX

But there is only is

What I've Tried

origin is ATL, JFK, LGA, BOS, DTW, MSP, SLC, SEA, LAX

origin matches (x) 'ATL','JFK','LGA','BOS','DTW','MSP','SLC','SEA','LAX'

I get no data in the resulting table for either attempt.

I think you may be hitting some issue, like adding all fields as a single string, containing commas i.e.: "ATL, JFK, ..." instead of "ATL" "JFK"

I've tried it with the Foundry Training Resources and it works fine, check the screenshot bellow:
