Editing Preset Description

Hi, I’d like to add more information to the description i put for a preset I created but when it comes up on screen I can’t see how to make a change. Text is greyed out and I can’t see an edit option. I may want to do this for other peoples presets as well. I’d be greteful for your wisdom. Many thanks, Simon

Solved. When I edited to sound and resave it I realised I could alter the preset description and save to the same preset name…
