Problem with "Save presets from Discover"

Hi all,

I tried recently to save some nice presets from "Discover" in Lightroom but it doesn' work anymore. Every times I click to a edited photo, and click to the blue tab "save presets",  a new blue tab said the preset has been created. However when I go in one of my image and I try to apply this preset is not in my "save preset". 

While I create my own preset evrithing is ok. Can anyone please help me?

I have restarted many times my laptop and the Lightroom appliccation.

Thank you,

Francesco
