Masking "Select Sky" is not saving to my photos

[JerBear89]

I love the new feature of being able to detect the sky and then choose a color for it.  I have chosen light blue and then I click the button at the bottom right that says "Done" and nothing happens. I have a lot of photos that look so much better with a blue sky instead of a white sky and I would love for them to be able to save. I am on a Windows 10 PC with the latest version of Lightroom Classic.  Below is the attached image and whenever I click "done" or click off the image it is not saving the mask edits. Am I doing this wrong or is this a bug?

The light blue color you have chosen is an overlay, and its purpose is to visualize the masked area, and to assist you when editing the mask itself – adding or subtracting areas. It cannot be used for editing. To hide/show the overlay, press O.

To edit the sky, select the mask, turn off the overlay, and use the sliders.

This is not the same thing as Sky replacement in Photoshop, which replaces the entire sky with something else.

Select sky does not replace the sky, but lets you isolate it and edit it.
