DD returning false (?) positive

System

Rather, I think DD thinks there's nothing to do, but this is my scenario (files attached below):

I have three tables who relate to each other in the following way: one QUIZ has many QUIZ_QUESTIONs, each of which has many QUIZ_QUESTION_CHOICEs. So, I have my DB schema and when I run it, DD tells me within 1 second that it "completed". The micro log tells me that 19 records were inserted into iwdeltracker, and indeed they were. However, there is nothing in any of the tables.

Wassup?

Attached are the relevant part of my config, the DCR, and the micro log.
