Values are NOT getting populated in the field even though I've selected them from a List collector

[Youssefarcher]

In a record producer, I'm encountering an issue with a 'List collector' field type. When I select values from the list, they don't appear to get selected. Instead, the field appears to have empty values separated by commas, as you can see in the attached photos.

Are you using any Variable attributes, other than glide_list?  Which column is the Display column on this table?  Is this field populated for the records you are selecting?

I am using just glide_list in variable attributes, I found that the values does not appear when I select them in the record producer. but in the table they get inserted as ID seperated with comma " , " as you see in the image

This sounds like an issue with the Display column then.  When you view a record in the list table, what appears at the top?  For example, when I view an Incident record, I see this:

So I know that Number is the Display column on this table (or the table it is extended from in this case) because it appears in the grey header below the table display name (Incident).  Therefore, when I have a List Collector using incident as the list table, I will see a list of incident Numbers for the records that I have selected below the lock icon.
