Debugging undefined Issues in Parent-Child Table Enrichment

I used the "Create item in another table" enrichment on a list within a JSON field. When I go to that item in the other table, one of the parent item fields is being populated with "undefined" when the parent item does in fact have that field defined. This also occurs when I try the workaround of "look up row in other table" to search for the parent (in this case a company) from the child (contact) tables. Suggestions?
