I forgot how to check the firmware version and instead of Globals + 1, I pressed Release + 1 and then the Record started to blink so in order to cancel whatever the OS was doing I pressed it as I would do when I want to cancel saving the preset, and like that, all my presets were gone.
If this is an OS function, I wish erasing user banks wasn't that easy, thankfully I had a backup since 1.5.0 update, so not all my presets are gone.
