Cases with Predefined Case Team report shows rows for each member of the case team for the same case

When generating a report on Predefined Case Teams,  the Case Number record appears multiple times. This occurs because there are multiple entries for each member within the Predefined Case Teams. These extra rows can lead to unnecessary repetition.

Steps to reproduce:

1. Login to the org
2. Setup > Report Types
3. New report type with primary object Cases and secondary object Predefined Case Team
4. Create Predefined Case Team and assign members in it.
5. Assign the Predefined Case Team to a Case
6. Go in Reports
7. Create new report created using report type (3)
8. On Group Rows use "Name"
9. Save and Run
10. In the report for a specific Predefined Case Team (4) you will notice the same case (5) multi times based on the numbers of members in it.
