I figured it out. I was modifying the wrong Flow above. I'm in a legacy Org with a ton of band-aid fixes, and they have 2 Flows named almost exactly the same, and they do nearly the same thing. I had chosen the Flow that was modifying the one named after the team I'm supporting.
I figured this out by going to Builder, then to Home and clickingthe page where the Flow is embedded. I clicked on the Flow from the embedded component there. Before, I was going to Setup > All Sites. Lesson learned :|
I thought about deleting this post, but people can still learn from it in a few ways.
