Imported color skies turn black and white in Photoshop Sky Replacement

[RicSenior]

I imported today 13 skies shots that I took this morning.  The skies had bright pink and orange clouds.  I imported the raw files into LRC, did some minor edits in the main editing panel to mostly to brighten each raw image and then exported them into a folder on my harddrive each as a DNG file.   In Photoshop I went to sky replacment, and clicked on the icon to import new skies. The new color DNG show up as  black and white skies when they are imported into the sky replacement module.  Is this a bug or am I doing something wrong or accidentally clicked some setting that turns them black and white.  Thank you for any assistance on this.

Hey, @RicSenior. Welcome to the Photoshop Community. I'll help you figure this out. What version of Photoshop, Lightroom Classic & the macOS are you working on?

In Lightroom, when you export as DNG, what options are you using? Please add a screenshot of Export As > File Settings panel.

As a test, try exporting the image in JPEG & check how they appear in Photoshop. It'll help if you export and share a few DNG files for us to test this. 

Thanks!

Thank you.  I did adjust my settings for export as DNG and was able to get the images to show up in color.

DNG file formats are not supported in Sky Replacement. Use flattened jpg for the source files.

Thank you for the response Kevin.  This morning I tried the process again and checked my export settings.  This time I was able to successfully export 13 files from LRC  as DNG. The first one I tried as an experiment worked just fine.
