Not strict hierarchical view of a project that has multiple sub-project in "Today" screen

I have one project that has multiple sub-project like this:
=>DWH (is administrativ Project)
xxx=>GENIO (is administrativ Project)
xxxxx=>GENIO V6
xxxxx=>GENIO V8

but the view in today screen is:
=>DWH
xxx=>GENIO
xxx=>GENIO V6
xxx=>GENIO V8

It's normal ? ... I think that is just a usability problem but this create confusion in hierachical project organization view!

Thanks

Ok thanks
