Too many matching records error in Visual Builder Add-in for Excel

Summary:

The requisition upload by Visual Builder Add-in for Excel ended in success but with a warning that there're too many matching records found.

I've checked each master data and value set values if there're any duplicated entries of each fields (e.g. supplier, category, deliver-to location etc) , but there aren't.

Do you have any idea why this warning occurs?
