BugFest environment match profiles: not show the fields for "existing record" FOLIO record types

Overview: When creating a match profile that matches to a non-MARC FOLIO record type (Instance, Holdings, Item, Order, Invoice), I'm not seeing the FOLIO record's fields in the "Existing record" section

Steps to Reproduce:

1. Log into Bugfest as abreaux
2. Go to Settings/Data import/Match profiles
3. Create a new match profile. Match to the item record
4. In the "Existing record" section of the match profile, click on the field list to display the list of item record fields.

Expected Results: Use should see the list of item record fields

Actual Results: There's no fields. Same thing happens for Instance, Holdings, Order, and Invoice.

Additional Information: See attached video

NOTE: This is not a problem in Fameflower, so appears to be an environment problem with BugFest. Ann-Marie will check with EBSCO Hosting to see who will help with sorting this out.
