UI GameObjects under the Safe Area are changing their position without being able to restore it when changing the Safe Zone position and then Reference Orientation

How to reproduce:
1. Open the attached project "SafeZone"
2. Open the SampleScene scene
3. Go to Canvas -> GameObject and change its position
4. In the Inspector, on the "Safe Area" Component, change the "Reference Orientation"
5. Observe the button position

Expected results: The button position doesn't change
Actual results: The button position changes and can't be restored even when undoing the Reference Orientation
