I don't see anything wrong in particular, apart from a few of the servers
responding with glue data in the answer-section, instead of the authority
section. I assume this is what you're refering to. This is correct behavior,
glue data is not an authorative answer and should therefore not be in the
answer section. This was a misimplementation in BIND prior to version 9.
