Device driver setting not restored from PRF

[sven-cpu]

Hello,

i wanted to upgrade my OV to the latest XCSoar version with integrated WeGlide features. I tried your build OpenSoar PreRelease v3.22.3 pre-2 which is working really well. I'm aware that using SkySight online data should be avoided.
Although i'm experiencing problems with the device driver settings. The selected driver doesn't get restored on reboot. It always switches back to "Generic".
Is there a problem with my system or is this a known bug? The settings seems to be stored correctly in the prf file, but somehow doesnt get restored.

Thank you

XCSoar versions not having the problem

System information

SteFly 5.7" CH57

Steps to reproduce the behavior

Goto NMEA-Device Settings. Set driver for device 1 to "LXNAV", restart the system, Driver for device 1 reverted back to "Generic".

Expected behavior

Device 1 driver should show "LXNAV"

Actual behavior

Device 1 driver reverted back to "Generic"

Do you have any idea what may have caused this?

Settings seem to be stored correctly in PRF file DeviceA="LX", but this doesn't seem to be restored on restart.

Do you have an idea how to solve the issue?
