Hello Kurt

If you go to Service Center, you will notice that the extension does not even appear in the list of modules/extensions. At least it does not appear on my personal env.

I think it is because those are actually System entities and System entities (like User) do not count for AO.

Is the extension consuming AOs in the environment you are checking?

Cheers!

Hello,

Sure it does. It's because I saw it on Service Center and because it consumes 10 AO's that I started this discussion. I also see it in Service Studio.

It does appear on several environments where the component in installed, both PE and customer environments. And I removed it on our partner environment and my PE and installed it again. Still there:
Our Partner environment:

My PE:

Very strang that you don't see it.

You are right. 

For some reason, when I filtered the list with (DB OR table) it didn't appear...

Weird.

Did you tried to remove it in your PE and see if the DBCleaner still works?

It is not used by the main module, but it may be used by the DBCleaner api that seems to be a system module? 

Otherwise, we have to wait for Miguel to throw some light on this.

Cheers.
