You do not have android:key attributes for your ListPreferences. I am
surprised this does not generate a runtime exception. But, as a result, I
doubt your values are getting saved anywhere.

It is expensive to keep reloading your SharedPreferences this way.

Your default value should be M to line up with the contents of your string
arrays. "Male" is a display value.
