Comment 2 for bug 1627127

It was just pointed out to me that the rev in the above comment is -1 with a null fingerprint, so that may be the cause. Specifying the edge channel shows the right resource rev:

    $ charm show ~bigdata-charmers/apache-zeppelin-15 --channel=edge id resources
    id:
      Id: cs:~bigdata-charmers/apache-zeppelin-15
      Name: apache-zeppelin
      Revision: 15
      User: bigdata-charmers
    resources:
    - Description: The Apache Zeppelin distribution
      Fingerprint: OLBgp1GsljhM2TJ+sbHjaiH9txEUvgdDTAzHv2P24donTt6/529l+9Ua0vFImLlb
      Name: zeppelin
      Path: zeppelin.tgz

I'm going to try releasing to stable to try to get the resource rev fixed and see if that helps.
