Preset settings not able to be copied

[#1]

I uploaded presets to Lightroom and I can't copy the settings. I reached out to the creator or the presets and was told this is a common Lightroom issue. Advice?

What do you mean by "I can't copy the settings"?

Presets are files with an .XMP file-type. (Prior to Classic v7.2 they were .LRTEMPLATE files)

They can be copied. (to copy to another computer, or to make a backup.)

In the Develop module there are several ways to 'Copy' a preset adjustments from one image to another.

You have- Copy&Paste, a [Previous] button, The [SYnc] and [Auto-Sync] options.
