@Mikkel Lund Knudsen Thanks for posting in our Q&A.
For this issue, we appreciate your help to try to sync the device and wait for some time to check if the device compliance status has changed.
To prevent this behavior that evaluate the system account causes the device to be "not compliant": For devices with a user signed in - assign the compliance policy to a User group. For devices without a user signed in - assign the compliance policy to a Device group.
If there is anything update, feel free to let us know.
