I'm in love with the editor but the presets menu worked only once, I was able to save a character and then it disappeared completely, clicking the preset button removes all UI elements leaving me with the pink background and nothing else :<
Check the folder with presets and see if there are any non .PNG images or any files that have (1) or similar in the name, that should fix it from all I know.
They are located at C:\Users\<username>\AppData\LocalLow\Stripey\GOMI\CharacterSaves\Preset
