Joystick Buttons not saving

For some reason the buttons on the right side do not save. Every time I configure them, click save, then open, they are back to this.

Has anyone else got this problem?

It happened to me a long time ago and if i remember correctly the problem was that for some reason MP save the parameters in one directory and on startup it reads them in another place. I can’t remember more precisely sorry, but maybe this hint will put you on the right track.
