User reference field is not displayed in implementation layer case designer
I used user reference field to select a specific user for the purpose of routing in Approval shape. I can select the user reference field from the dropdown but I can see nothing in the dropdown when I select the user reference field for the routing. I have imported the same case type rule from the framework but there is obvious descrepancy in the routing configuration while just imported.
What is causing this issue and how can it be resolved?
