P: When applying the Warm Contrast preset the applied lens profiles are removed

meine Vorgaben funktionieren in LRCC7.5 nicht mehr und Objektivkorrekturen ebenfalls nicht. LR ist mit der heißen Nadel gestrickt.

Just updating to LR 7.5 didn't fix the issue for me. I had to update Photoshop CC (19.1.6) before the "Creative - Warm Contrast" preset got updated correctly (presumably because the preset is "owned" by Camera Raw?).

Lightroom Classic CC 7.5 was released today and should address this issue.  If you don’t see the update in your Creative Cloud App, hit the [Ctrl/Cmd]+ [Alt/Opt]+[R] to force a refresh. 

Give the new version a try and let us know if it solves the issue. 

Alternatively, open the .xmp file in a text editor (TextEdit or Notepad) and copy/paste its contents here. This will let us determine if this is a bug and what an appropriate workaround might be.

"The preset only has changes to the profile camera setting and calibration process."

Can you please share the preset here?  In the Presets panel, right-click it and do Show In Finder / Explorer, then upload the .xmp file to Dropbox or similar and post the sharing link here.

I found a problem with batch processing when I apply a preset I created. The preset only has changes to the profile camera setting and calibration process. When I apply to a image it works fine. When I select all images and apply the same preset to all photos, with the exception with the selected image, all other images remove the lens profile corrections. I've double checked to make sure lens profile corrections options are not apply for that preset and I also created a preset too so that lens correction does apply and regardless of preset settings, batch processing removes lens profile corrections on all other images. Is anyone having this problem? I never had this problem before, only after recent update.

I am on it; I will get a bug logged. 

To clarify, I'm not an Adobe employee. It's good that you posted this bug report.

I figured you folks already knew  🙂

Right, "Creative - Warm Contrast.xmp" has the line:

   crs:LensProfileSetup="LensDefaults"

which is the cause of the problem.
