Read three or four posts up, in this thread.
Also see Kinney's milb.com page. I had assumed the goofy transactions history there (e.g., "assigned to GCL on 7/11, signed on 7/16, assigned to GCL on 7/20) was the usual mlbam incompetence. But perhaps something else was going on - for instance, maybe the Commissioner's Office had some issue with Kinney's original contract, and the Phils had to "re-sign" him - so he actually DID sign on the 16th? If that's the case, that would explain why Kinney "disappeared" after 7/11.
