You can also work around the bug mentioned by g00dy this way:

Get the set from sharedPreferences and save it in a variable.

Then just delete the set in sharedpreferences before adding it again when saving.

SharedPreferences.Editor editor= sharedPref.edit();
editor.remove("mSet");
editor.apply(); 
editor.putStringSet("mSet", mSet);
editor.apply();

Make sure to use apply() or commit() twice.

Alternatively, if you are working in Kotlin simply :

PreferenceManager.getDefaultSharedPreferences(applicationContext)
    .edit {
        this.remove("mSet")
        this.apply()
        this.putStringSet("mSet", mSet)
    }
