I agree, and that's one of the main goals in LODD, to identify such issues. Part of the group's focus is on developing usecases to make sure we have the right data and the right linkages. We have already identified a few problems and fixed them, but we have missed this one (and probably many others) which also shows this part of the data hasn't been in any of the usecases and applications so far. And remember that this is still a preview release of the data, we hope to gradually remove these anolamies, and we certainly need your feedback.
