Sorry, but the screen shot you provided isn't going to do me any good. I need much more information before I can attempt to diagnose your problem. I need the log file (it will be in the same location as the pkg file you are exporting and be named something like PackageFileName_ResultsX.log).Next, this is a data deployment issue, not a structure issue. So you can introduce a bug into the system yourself by having empty data tables or using the child nesting and the structures aren't deployed, etc.
The first thing to do on something like this is to back up and remove each of the data deployment items until you know where your problem is. Once you know which item is causing your problem, then make sure that the setup of the deployment data is valid (i.e. pulling from the proper location, pulling the right records, etc.).
