Distributed Collaboration legacy in Groups

[JonathanMcD]

We've just deployed a new base enterprise and as part of this deployment we wish to share data across AGOL to Portal. Setting up a Distributed Collaboration is fine, and works well, however, I created a collaboration with an existing AGOL group to test and I now want to redefine and setup our collabs.

I moved backwards through the process, working in Portal to leave the workspace and collab, then in AGOL, however, the Group I selected still shows its content is part of a Distributed Collaboration. 

Is there a way to change this?

Below is a shot from another group that has zero content and no collabs setup in AGOL but the distributed "tag" remains.
