Settings not saved when powercycling (2.9.0 Beta 9 and 10)

[Arthur-de-Partuur]

Problem
For 2.9.0 beta (9 and 10) Upon power reset (off-wait30sec-on) some settings are lost, such as:

• WebAPI version (reverts back to 1.0)
• Itho status update frequency (0-65535 seconds): reverts back to 60 sec
• possibly others as well but did not test

Steps to reproduce the behaviour:

1. Power cycle demandflow
2. wait 20 sec
3. power on, wait untill fully operational (I wait for 5 minnutes)
4. Check system setting tab

Expected behaviour
I expect the the settings (particulary api and update frequency) to stay at the set point.
Current behavious causes issues with HomeAssistant / Node red
