Noticed in React testing, that if you have a criteria applied to a cleanup policy that is specific to certain formats e.g. "Release Type" and then change the format to one where that criteria doesn't apply (e.g. Raw in this case) and save, you'll get the below error.
This was not a problem in the extjs implementation because you could not change format.
Repro steps (on react build):
1. Create a cleanup policy of format maven2 w/ release type checked and defined. Save.
2. Edit the format to raw. Save. BUG: Should get the error in nexus.log and another on screen.
Workaround: Uncheck the policy first.
