It looks like you found a work around for this after speaking with Christian G. He said you solved it by exporting all of the Associations and all of your Filesets as a CSV. You then built an Excel file to do some calculations for you. I have created a Feature Request for a way to quickly/easily list Filesets that do not have any Associations. FF-991.
