Agree with above suggestion as that would help identifying the content/bundle which is not getting replicated. With GUID its difficult to troubleshoot all the failures and takes away lot of important time.
I think *anytime* you are reporting IDs that have human-readable names attached, like bundles, the human-readable name should *always* be included. Honestly, of what use is a series of generated letters and numbers to the end-user admin that deals with actually-named objects?
