[ovirt-users] How to tell a migrated engine it is not running as a hosted engine anymore?

I migrated a hosted ovirt-engine to a standalone machine. To do so, I created a backup with scope=all and imported this back-up into a newly installed engine. Everything was working fine. Not much later, I made a mistake and wanted to start over, so I decided to do an engine-cleanup and re-import my back-up. However, when I perform the engine-cleanup, I get this error message: [ ERROR ] It seems that you are running your engine inside of the hosted-engine VM and are not in "Global Maintenance" mode. In that case you should put the system into the "Global Maintenance" mode before running engine-setup, or the hosted-engine HA agent might kill the machine, which might corrupt your data. This is not true. The engine is now running as a standalone server. There must be a config parameter somewhere in a config file or in the database that tells the engine what mode it is running in, but I haven't found it yet. I can't find any documentation for this issue, all migration guides tell you how to migrate from standalone to hosted engine, not the other way around. How can I fix this?
