Selecting child records from enumlist to display inline

I have three tables - Parent/Child/Requests. The requests table displays requests for a parent record and I display the child records as an inline table in the form. However, I need to be able to select certain child records to display, instead of all child records. I’ve figured out how to select the records using an EnumList with Type Ref, however, the result shows up as text, instead of inline records. What am I missing?

I noticed this behavior/bug when I was trying to set up slices to set up read only inline views. After several tries of deleting and recreating the slices and REF_ROWS, I was able to get rid of the result showing up as text instead of inline records.

It is frustrating to debug these kinds of issues, to say the least.
