I think I found a bug here

I had a profile with a child profile, downloaded to iOS (iPhone, iPad and iPod)
Using List mode
The profile had the proper ">" to indicate the child profile and pressing it did view the child.  Als the parent had "Boc Set Contents" that led to the same screen

I then deleted the child profile on my Desktop
I then Updated my profiles on the devices

All devices still show ">" and the parent profile shows "Box Set Contents" (which there isn't one anymore).  Hen selecting either it points to a blank screen.

So when Box set contents are completely removed using the Windows version the updated is not updating the devices correctly
