Declarative Onboarding / Configuration not or partially deployed and configuration deletion

Hey guys

I recently experimented with DO and I am kind of confused. I installed the DO app as described in the guide and tried a simple DO declaration. The only configuration that changed after the Postman POST request were DB vars for UI advisory (enabled, color green, hostname /Common/hostname). Network interfaces, hostname, NTP servers etc. were not changed.

I changed the advisory stuff from color green to blue and the hostname to /Common/bigip. It worked out in the first place but some time later it switched back to the old configuration without hitting a key.

This is a weird behavior. I searched the Internet to wipe the DO configuration but found nothing. Can you give me some hints about what I am doing wrong and/or deleting the DO configuration?

This is my JSON declarationfrom the F5 DO example, slightly eddited.
