Store Icon in Outlook - Cannot select retention category

Servers are EV904.
EV Outlook Add-in is 10.0.4.1189.

We're testing the Store button. I'm trying to find where in our desktop policy - or elsewhere - why the retention category defaults and will not allow the user to select another retention category. Documentation states: "Click the Name arrow to see more options."
 

If it matters, our backend is Centera in governance mode and Centera handles the retention names and values, not EV.

Thanks for any idea.
