Issue
Creator Hub Data Stores Manager appears empty even though the game loads saved data.
Cause
The wrong universe, store name, scope, environment, or key prefix may be selected. Ordered stores and wrapper libraries can also organize keys differently than expected.
Fix
Confirm the universe ID first, then match the exact DataStore name and scope used in code. Check whether Studio is using API access and whether the project writes to a test namespace. Search for the final composed key, not only the player ID.
Verify
Write a uniquely named test record and locate that exact value in the manager.
