This is super impressive!

I'm probably doing something wrong. Can someone let me know?
I was curious what state Possum has been played the most.

I entered 5-28-22. (Wharf Amphitheater, Orange Beach, AL)
I scrolled to the map at the bottom.
I deselected every song except Possum.
I see the green dots all over the country where Possum was played. (including Orange Beach)
However, there isn't a green dot south of Birmingham, AL to indicate that Possum was played at Oak Mtn Amphitheater.

What did I forget to do?
