Duplicate Entries in /deviceManagement/detectedApps API Response

Hello,

When using the Microsoft Graph API endpoint https://graph.microsoft.com/v1.0/deviceManagement/detectedApps, I am seeing duplicate entries with the same "Id" for certain detected applications. These entries have the same or similar displayName (e.g. Microsoft.LanguageExperiencePackcs-CZ and Microsoft.LanguageExperiencePackcs-cz) and the same properties such as version, sizeInByte, publisher and platform. They only differ in deviceCount.

Why does the API return duplicate detectedApp entities?

What is the recommended approach for deduplication or aggregation when reporting on detected apps and their deviceCount?

Is this expected behavior, or could it indicate a configuration or data issue in our environment?

Any clarification on why these duplicates appear and best practices for handling them would be greatly appreciated.

Thank you!
