As far as I can tell from your description and the information provided this is a Cinder issue, though I can't figure out what would cause that. The Cinder team is more likely to be able to track down the problem.
If this were a dashboard problem you'd be seeing errors messages when you try to create the volume (e.g. the API would throw an error or reject the API call).
