AutoFocus Miner problem

[austinrappeport]

I am getting no indicators when I run an AutoFocus miner on an AutoFocus search to pull in the files my Firewalls submitted to Wildfire and did not block.  The query I'm running is:  {"operator":"all","children":[{"field":"sample.malware","operator":"is","value":1},{"field":"session.status","operator":"is not","value":"blocked"},{"field":"session.upload_src","operator":"is","value":"Firewall"}]}

However, when I run this in the AutoFocus search I get plenty of results.  See the attached screenshots for a comparison between the two.  I even tried to change the Prototype configuration to set the initial interval to an extremely long time, because some of the results are more than 24 hours old.  Still nothing pulls back results.  

Any idea whats going wrong?  Can minemeld not properly run searches on AutoFocus session metatdata?  Is this some kind of bug or am I just missing something obvious.  Thanks for the help!
