I played around with the tool a little bit more and I am not really shure what happens. I think the main problem is, that in the source added transitions are not shown in the diagram. After then adding them there I had some confusing with Transitions (some duplicates, some invalid, ...). So I removed all transitions from the source xml, reopened the diagram and draw everything by hand. after that, the diagrams looks like it should. If you can fix the problem, that added transitions in the source are shown in the diagram, maybe the biggest problems are gone then...
