Fix Android App's Duplicate Listings Issue

My Android project is currently facing an issue with duplicate listings. Specifically, it's returning different content but with the same ID. This issue is primarily observed in the order data endpoint.

The task is pretty straightforward. I already know the cause and just need a capable developer to fix the known issue. Filtering is to be done on the frontend.

Ideal skills and experience for the job:
- Proficiency in Android development
- Experience with debugging and fixing duplicate data issues
- Familiarity with modifying API endpoints
- Understanding of frontend data filtering
- Knowledge of handling order data in applications
