Are you a subscriber to a CC Photography plan?
Install Classic v7.5 from the CC Desktop App,
Try the [Right-click] in the Develop module- Presets "User Presets" Group folder and select [Import...]
Navigate the Finder dialog to the purchased presets and [Import]
I'm having the same issue...
it doesnt want to read the presets
What error message do you see?
Are you using the method below?
Your screen-clip is not the "Preset Import" window I would expect to see. (Are 'greyed out' files in a Mac Finder view something normal?)
What folder are these .lrtemplate files located in your computer?
1) In the Develop module- Presets Panel- [Right-click] the "User Presets" Group folder and select [Import...]
2) Navigate the Finder dialog to the purchased presets, select the files to Import, and click on [Import]
3) Restart Lightroom.
The more I look at your screen-clip, the more I think it might be a Mac problem (I use Windows)
