Bartok lose configurations

Occasionally my Bartok loses the configurations like filter choice, display settings etc, and the saved configurations dissappears as well, which means I have to set-up everything again. Rebooting with power off has no effect. Settings for Tidal is not affected. I leave my Bartok on all the time (no standby).

How can I stop this from happening?

Configurations saved;

And then no configurations available;


I also had similar problems. The configuration files I have previously saved have disappeared.
