I have already replied to your ticket that was opened on the same question, so that I am pasting my answer here for the rest of the community:
I have tried to reproduce the mentioned issue but to no avail - the drill down is going through all the mentioned levels. You can watch the short video test and then tell me what I am missing. Since the provided sql data sources are not available I have created a sample DataTables that are binded on each drill-down.
If the above step, however, is not helpful I can suggest that you try to reproduce the issue with the attached VS example and then send it back to us, so that we can make an investigation locally.
In the future, please post only one thread per question, because this will keep the conversation concise and in one place, without duplicating content and effort.
