I can't edit\delete presets

[alessioadams]

Hello and thanks for this extension! :)
Sadly I couldn't edit my presets, so I tried to delete them but they never go away. Not even after I uninstall the extension through the manager or deleting the files. Everytime I install the extension again, the panel appears exactly as in this screenshot.

and this is how the options panel looks like:

If i try to create new presets, they won't appear.

I think there are some files to delete in order to make it work again. Obviously the folder \Plug-ins\Panels\Save Panel is not the only one I need to delete.
Where does it save the presets?

I'm using PS CC 2014 on Win7.

Thank you in advance,
Alex
