Web UI: "You don't have permission to exec"

Nomad v1.6.1

I have a Nomad cluster with multiple regions. Typically I am able to open the Web UI to access the “Exec” feature. Recently, I noticed that as soon as I switch regions (using the “Region” drop-down menu), I am no longer able to use the “Exec” button on any of the jobs that are running. The button is grayed out and the hover text says, “You don’t have permission to exec”.

If I kill my Nomad session and launch the web UI again, the “Exec” button is available to me again.

Is anyone else seeing this?
