Setting a different field to Display has the same results.  This isn't a variable on a catalog item that I'm referencing. It's the OOB references to RITMs.  The number field, which is set to Display is coming from the task table, and references to all other tables extended from task appear to be working as expected.
I've also looked for Dictionary overrides on this field for the sc_req_item table and did not see any.
