This is the Behavior of nslookup and that DNS client service, you will not
get this behavior if you add a trailing "."(dot) to your queries. This is
not a problem with your DNS server, it is the client, it first appends the
Primary DNS suffix, then it appends the parent of the Primary DNS suffix
(ms.sg in this case), and will continue to devolve until it has appended the
last two level domain, if you will append all queries with the dot, the
client will not append suffixes. Try nslookup with the -d2 option to see
what names are sent to DNS.

If you follow my instructions it will stop.

The Domain "ms.sg" has a wildcard record in it that will redirect you to
some kind of Website administration page if you resolve a name that does not
exist.

Look at some of the names I queried for,
