Hi Rose,
Just to be sure, when you switch to the Group Model those references are missing/read, but if you switch immediately to the master/default Model those same exact references are attached? If so, that is odd since these are two Models within the same DGN file, and, the Group Model is simply a copy of that master Model which would normally retain everything from the original.
