So the issue reported by davidtuck in the
opening post to this thread is not really the issue. The issue is that the agent stake's building scheduler for the location cannot edit events made by the sharing stake, or the sharing unit of the sharing stake. The second part of the issue is the members of the sharing unit or sharing stake cannot view events at the location because the location does not appear in "Available Locations". Yet when the sharing unit or stake creates events on a sharing ward or stake calendar the agent stake location is available to allocate resources.
This
other thread is a better discussion of the issue.
