If you have access to the system terminal or one of the SSH add-on terminals, you can try running the following commands to trigger an update:
ha supervisor reload
ha supervisor update
A message appears that no update is available.
Host reboot = No change and the same problem. 
Edit: The error message and the wrong version-Nr. are still there
but the “system is not healthy” message is gone.
Edit 2: After the Core Update from 2022.2.9 to 2022.3.3 the errors are gone.
