I am experiencing this issue as well. The last package I had work correctly was back on 16th April. It's only this week that subsequent packages have not appeared in the enterprise dashboard (aedash.adobe.com)
I have logged a case with Adobe Support via the support button in the dashboard.
I am running Mac OS 10.10.3 with an Adobe Enterprise CC serial key, and CCP v1.9.0 build 14
Edit: I have tried purging the CCP cache as well via CCP preferences (click on name at top right of CCP app when it launches, choose Preferences) but with no effect.
