CM12 Collection Folder Phenomena

[ibrafe]

Hi

 

I am seeing a very strange behavour with our CM 12 collections. I created a folder called Departments and created collections underneath it that queries Dept OU.

 

 

Random collection are being moved back to the Device Collection and everytime I move them back. They reappear back under Device Collection

 

Below is the collection setup:

 

Each collection under Membership rule has "Use incremental update for this collection checked and Schedule a full update with a schedule to occur every day. All the collection has a limiting collection pointing towards "All Workstation". (This was created to exclude server OS)

 

We have not run any discoveries so NO PCs are being discovered.

 

 

Any ideas?

 

Thanks
