Error when opening classroom.blend with 2.8RC

Using OSX 10.14.5 latest blender 2.8 RC
When I try to open classroom Demo file with the latest Blender 2.8 versions I am getting a bunch of errors and objects are not linked correctly. How do I get around this if this is no longer supported in current blender or is this a bug?
