2.6.8 - Configuration not always saved

Hi there,

I think there is a minor bug in 2.8.4:

If you change the battery type (German: “Batterietyp”), e.g. from “Automatic” to “Manuel” or vice versa and you leave this dialog via the swipe-to-the-right-gesture, then the changes won’t be saved. They are saved only when you leave the dialog using the back-button.
