Some presets are imported but do not appear in Lightroom

[jairrc]

Hello!
I have 8 Presets that I received in an editing course I took and, when importing them into Lightroom, a group with the presets is created, however, only 2 of them appear in the group. The other 6 do not appear, even though they were copied to the "AppData\Roaming\Adobe\CameraRaw\ImportedSettings" folder along with these 2 that appear (I'm using Windows). I've already tried opening the folders through the Preferences option and pasting the files there, I've tried importing the Zip file with all 8 presets and nothing has worked. Only those 2 appear. I looked for information about this on Google and here in the community and found nothing. Would anyone have any tips on what else could be done to make them appear in the Presets list?
Thank you very much!

I discovered the cause of the problem. Comparing with those that appear in the group, I identified the block in the image below, which contains a key "crs:Name="verde5"" that must be conflicting with other installed Profiles that have matching names. As that block did not exist in the Presets that were imported, I removed it and then the Preset appeared in the list.
Problem solved.

The root cause of the problem is that the problem presets referred to an enhanced profile named "verde5" with UUID "D67354F324324F2A9400357C90A8F8F6". That profile hadn't been imported into your LR, and in such cases, a longstanding bug in LR causes such presets to not appear in the Presets panel.

When you deleted the line 'crs: Name="verde5"' from the preset, you were effectively editing the preset to no longer use that profile, which will affect its appearance when applied to a photo.

The correct solution is to find the enhanced profile named "verde5" and import it.
