[Photo 2.5.7] Shadows & Highlight overlays checkmark are incorrectly active

[LCamachoDesign]

This one is a bit hard to explain, but easier to see. When you first create a tone mapping overlay, it is supposed to be translucent red until an edit to the mapping value is made. This turns off the temporary red overlay and starts displaying the changes. This particular switch does not work well if you do changes to the Shadows & Highlights values on the Master overlay, and then create another overlay, be it brush or gradient.

Steps to reproduce:

1. Create or open a 32 bit image that has easily identifiable shadows or highlight areas
2. Switch to the Tone Mapping Persona
3. Do any adjustments to the Shadow & Highlights that's easily visible
4. Create a tone mapping overlay, can be either brush or gradient
5. Notice the Shadow & Highlights section is already active
6. Do any changes to this section values, and only this section, don't touch any other
7. Notice there are no changes in the image
8. Notice the red overlay does not turn off
9. Turn off the checkmark for the Shadow & Highlights, turn it on again
10. Notice the changes are now applied to the image
11. Notice the red overlay disappeared as expected

To make it easier to test and isolate this, I turned off the other sections in the Master overlay, but this step is not needed to trigger the bug. Video included showing the steps to reproduce.

Thank you!
