XO24 how to delete 1 user preset?


On the XO24 how do you delete a user preset, I've been tweaking my presets and have a few "test" presets i saved while setting things up, now I want to delete the ones I don't need and there doesn't seem to be a way to do it, I've looked in the manual, but nothing.

I just want to delete 2 presets, not ALL the user presets.
