Steps to reproduce:
1. Open new project
2. Check the Camera component field "FOV Axis" (Should be Vertical)
3. Set it to Horizontal
4. In the inspector, click the "Reset" button for the component to reset it to default values
5. Axis remains unchanged.

Expected: The FOV Axis should get reset to its default value
Actual: Other values are reset, but not the axis
