If you've applied a local-adjustment preset X to a mask and then use the local Point Color tool, the preset menu doesn't change to show X (edited), and you can't update X with the current settings.
To reproduce in LR 13.1 / Mac OS (also see the attached screen recording):
1. Create a Linear Gradient mask.
2. Set the mask Exposure = -4.
3. Save as a local adjustment preset X.
4. Change any other local adjustment other than Point Color, and observe that Preset: changes to X (edited). Resetting that adjustment to its default value changes Preset: back to X.
5. With Point Color, use the eye dropper to select a color. Then change all of its sliders to non-default values.
8. Observe that Preset: still shows X rather than X (edited), and the Preset menu won't let you update X with the current settings. This is incorrect.
