We're Server customers who are putting a toe in the water to explore JSM and Confluence Cloud to see what they can do for us potentially.
I need help/direction in cleaning up our "Atlassian administration" page, which is currently showing 3 "Organizations".

We should only have 1 "Organization", which is the first one shown above.
The attached image shows what we have and what I suspect we need to do:
- Delete the "jira-core" org (we do not use it)
- Delete the 2nd of the two "organizations".
Please advise on how we can do this.
