Smart Editor Fields

[RichBell]

How do I alter the Smart Editor Widget to enable multiple fields to use a drop down button and select unique values?

I can only get the first field "ORDER_TYPE" in the attribute list to work with drop down button.

See image...

I am having this same issue in October of 2021, for some reason only 1 field has a drop down list, how can I enable other fields to have drop down lists? I checked the data and the one field that is working doesn't even have a domain.. I am using ArcGIS Enterprise, and trying to set this up for Updating existing records, not creating new ones...
