Feral Heart

A while ago, I created a preset on preset 12 and exported it ingame so I could use it. Later, I decided to replace it with a new one. But when I deleted all the preset files in the preset 12 folder, made new files, and went to preset maker, it showed the old preset 12 that I had deleted when I clicked on the preset I exported in the list of presets. When I clicked on the preset 12 that I hadn't exported, it just showed up yellow and black. If anyone could give tips on how to fix this, that'd be great! 
Thank you!
