Adjust an image in Camera Raw. Save the current settings in a snapshot. Continue editing the image and save another snapshot. Right-click on the first snapshot and rename it. Result: The first snapshot will get a new name (as expected) and will also be reset to the current settings, losing the originally saved settings (which is not expected).
Applies to: Camera Raw 9.9 (and possibly also earlier) under MS Windows 10.
Can't replicate that here on Windows 10 and Camera Raw 9.9. Renaming works as expected with no impact on the actual snapshot settings.
