Set Column Value Not Working in Button Bar

My Data Editor auto-updated about 20 minutes ago and, since then, I’ve been unable to use Set Column Value in a button bar. I’ve refreshed, and I’ve signed out then back in, but the issue is persistent:

The action is assigned to the LEFT button, which is “grayed” out (above). I am able to replicate the issue again after switching the custom actions from the LEFT button to the RIGHT one (below):

Anyone else experiencing this? It was working just fine prior to the auto-update.

Thank you!
