Troubleshooting duplicate records in Crystal Report

Hi,

I'm encountering an odd issue I've never seen before.

When I run my Crystal Report, every record is being duplicated. Normally, this would seem to indicate an issue with the way data is being pulled/joined, but when I run the stored procedure, there are no duplicates. These duplicate records only display when the report is run. Any ideas on how to troubleshoot something like this?

Thank you!
