Android car radio app not remembering stations

Hi there,

Ik have a radio in my car that is fully android 4.4.4 from an unknown chinese brand named joyous. All is working fine, except there is one thing that is bothering me, and that is the radio app is not remembering my presetted radio stations after it has been fully shut down. Im 100 percent sure it has continious power (it has been measured). Every other setting there is, it remembers, it continues playing my mp3 files where i left of, it remembers which source i used last time etc. Only the radio presets will not be remembered. Is this a known issue and are there other apps (apk) that i can install to try if these will remember there settings?

My unit has the following specs as i cannot post links yet::
