Reproduction steps:
1. Create a new “com.unity.template.urp-blank” or “com.unity.template.hdrp-blank” template project
2. Open the Project Settings > Player Settings > Other Settings
3. Look for the Active Input Handling setting
4. Observe the setting

Expected result: The setting is set to “Input System package (New)”
Actual result: The setting is set to “Both”

Reproducible with: 6000.0.51f1
Not reproducible with: 2022.3.63f1 (Not expecting the New Input System package), 6000.1.7f1, 6000.2.0b5 (The result is as expected)

Reproducible environments: macOS 15.5
Not reproducible environments: No other environments tested

Notes:
- Using “Both” instead of “Input System package (New)” might affect performance
- When using “Both” a warning pops up saying that this might cause issues when building for the Android Platform
