Unable to retrieve Biovia Workbook audit history or workflow information using SQL components (Oracle)

I'm using Pipeline Pilot v9.2 and I've been using the SQL General component to query our ELN's content (properties) without an issue.  But when I attempt to look at the schema for the audit history or workflow history I get nothing but emptiness.  No errors in my queries, but no results either.  Anyone else have a similar issue?
