I looked into this issue more and there have been multiple CARs filed for this issue as well as other empty cluster references causing errors. The most recent CAR specific to this issue was set at a higher importance than the others so I would say that R&D knows about it and is out there working on it. The error is genuine, but when it is displayed it is flawed. Fixing a non-related error should not cause this error to go away.
What Matthew Kelton suggested at the top of page 2 is the correct fix to this problem, you will need to populate those clusters.
