Issue:
After clicking Save Changes when removing collaborators from a plan or pathway, the collaborators are added back to the plan or pathway.
Cause:
Not all collaborators can be removed at once.
Resolution:
At least one collaborator needs to remain on a plan or pathway to ensure someone is responsible for the content. If the only collaborator of a plan or pathway is no longer part of the organization or moved on to another role, either delete the plan or pathway or add someone else as a collaborator instead.
