Online vibration Call notification

After upgrade to ver 21.19 is not possible to set "Beep" and vibration. Since version 21.19, it is not possible to set the notification to beep for calls. The slider in the settings always returns to the beep (sound) position back to the inactive state. Other notifications do not cause problems, only calls. Vibration works. Does anyone have the same problem? Thank you, Lukáš.
