Problem with saving setings

Hello everybody.
Excuse me for my english.
When I use the media player classic in windows 10, the settings are not saved.
For example, I set "playing next file" after reading a file and quit the player, the setting is automatically reset at " do nothing" the next time I use the media player.
Does anyone have an idea to solve this little problem?
Thanks.

This only applies ONCE:
Menu > Play > After Playback

This applies EVERY time:
Options > Playback > After Playback
