There are a lot of configuration errors in the domain
wadsworth.org. Discrepancy in the list of authoritative name servers
between your zone and the parents, unresponding name servers,
non-existing name servers (!). I suggest to fix that before adding
things.

Which is non-standardized and a specific feature of some DNS
hosters. In your case, the fact that you use BIND on the primary is
not the only factor, you would also have to consider your many (!)
secondaries.
