What is the purpose of the Plan Creator or Owner Field in the Quality Inspection Plan

When trying to create an Inspection Plan in the newer Redwood UI, there is a field for Plan Creator or Owner that must be populated in order to continue. There does not seem to be any values available to me from the drop down list. What is controlling this field and how can I select a Plan Owner or Creator? I would have though it would have defaulted in based on the user creating the plan, but it does not. — Currently Testing in our 25A environment.
