MediaBay shuffle result shortcut broken?

This is a very niche question, but I’m trying to shuffle my MediaBay result with a shortcut (rather than using the shuffle result button).
In the key command’s dialogue, it is clearly under media → shuffle results but when I’m using my key command I’m just getting a yellow error saying this shortcut is unavailable.

(Pressing the button with my mouse does indeed shuffle the results.
What would seem to be the conditions to have this shortcut available?
Is the key command not tied to the media bay or something?

I’m lost here.

Please help :pray:t2:
