Nobody can see your result detail but you and the technicians, but surely you've seen e few issues reported on the current beta 6.08. The techs can decide to ready a cancel message when work is found faulty or redundant. If the client contacts the servers it fetches this instruction and does so without wasting further cycles.

We know the log is empty thus lacking information as to why. There are a few changes / additions underway regarding Result Status, thus a 'Cancel' condition may come and the 'Inconclusive' may get a rename due similar to 'Abort', causing linguistic confusion.
