Clarification of "what" is expected.

On Sophia Burtsfield, LDLG-1LS, PQS is coming back and stating that "The birth only has 1 of 2 expected tagged sources."

What are those two tagged sources?

Same for her name, "The name only has 1 of 2 expected tagged sources."

Again, what are those two tagged sources?

I guess what I am getting at is this seems "only has 1 of 2 expected tagged sources" is a bit like sphinx-like riddle to users. Could it be written more clearly?
