Hi Scott,
Go to MDGP | Tools | Setup | System | Alternate/Modified Forms and Reports. Select the ID then select GP for Product then Reports for Type.
Expand the Financial series then look for the name of the report you're printing. Expand it.
There will be 2 options there, one has (Modified). If the one with Modified is selected, then that means you're using a modified report.
Let me know if you have further questions.
