Device Collection Properties - "Edit" button greyed out


I'm trying to go into an existing Device Collection's properties > Membership Rules to edit the queries that make up the collection.
However, the "edit" button is greyed out.

This is the case for nearly all the device collections, but not all of them.

Is there a way to fix this without upgrading? We can't upgrade yet as we're trying to get by with this version for this week for last deployments of packages, then we are free to wipe and start over.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I think there is no trick. You have to upgrade.
What if you create new collection and include the NON-EDITABLE collection in to?
