I think there is still something broken.
Using edu.bs, which seems to be working, the name ub.edu.bs can be resolved.
If one queries for the SOA at edu.bs, the negative answer is the right answer –
showing the SOA record owned by bs.
Asking for the SOA for com.bs., the responses I see, from all three servers for
bs., have an authority section pointing towards the NS set for com.bs. This
makes little sense as, if there is no soa record for com.bs, It can’t have an
ns set.
It’s hard to tell remotely, but, you probably want to set up com.bs just like
edu.bs. But that’s not very reliable advice, based on not knowing the full
intentions nor the contents of the zone file.

Subject: ENT NXDOMAIN problem at .BS nameserver ns36.cdns.net
The .COM.BS is an empty non-terminal with various child domains
registered beneath. The "ns36.cdns.net" nameserver for .BS responds
with NXDOMAIN to "com.bs" qname-minimised queries.
This in turn can and does sometimes lead to NXDOMAIN inference for the
child domains.
This nameserver needs to be withdrawn and fixed before it is returned to
service.
