I have a dataset - "Gallup Park, Ann Arbor, MI, US" - which I submitted for publication. In the active project space, this dataset has dataset level metadata - abstract, creator, experimental site, contact, etc. on the dataset level. When I click "Publish" and review my dataset in the Staging area - it shows no metadata saying "No metadata available for this resource". I also have no access to the dataset level metadata within the file section where I can only click on a particular file that's part of my dataset to potential see the file level metadata (which files in my dataset do not have). Could you please see why my dataset level metadata hasn't been transferred to the Staging Area?
