Lightroom CC: Tone curve and other bugs

Please see https://helpx.adobe.com/lightroom-cc/kb/tone-curve-presets.html for additional information. 

We've identified the issue with the automatic adjustment of sliders and have a fix on the way for the next release. 

The tone curve not having Medium and Strong Contrast is also known and we are working on a fix. 

I found another bug with the Radiant Gradual filter; when using it if you click invert it applies the filter to everything outside of the circle, so for it to apply it to the circle you put around the subject you need to not have the invert option clicked.

Will all the curve presets come back in the next update too? Not only are Medium and Strong contrast missing, but all the curves I've saved over the last couple years are also missing.

Marcus, 

At this time I would say that the Medium and Strong Contrast Tone Curve presets or Tone Curve presets in general will not be returning to Lightroom CC on any platform - Desktop, Mobile Device or Web. 

Presets in the Tone Curve panel are redundant in the Lightroom CC universe as any tone curve can be saved as a conventional preset which will sync across the ecosystem. It no longer makes sense for most users to have a tone curve save-able in more than one place. To streamline interfaces and make the tone curve process consistent, the ability to save a curve-only inside-the-panel preset has been removed. Going forward tone curves will be saved as a normal preset. 

Lightroom Classic CC will retain its current behavior and allow tone curves to be saved either way. 

For those of you used Photoshop's tone curve to create saved curves or have saved curves in the past via Lightroom Classic CC or an earlier version of Lightroom CC, your option to restore your existing tone curves is to:

1: Open Lightroom Classic CC.
2: Load your saved Tone Curve via the Tone Curve panel.
3: Save a Lightroom Classic CC preset in the Presets panel. 
4. Locate the preset and import it into Lightroom CC where it will sync across the Lightroom Ecosystem. 

We are working on a help document which should contain links to download the previously supplied Medium & Strong Contrast tone curves as a conventional preset.
