It is not legal for a DNS CNAME RRset to coexist with other data for
the same domain name. Nor should you have multiple CNAME records for
the same domain.
If "mdw.zmbc.edu" is a host with "A" records, it must not be a CNAME.
If it is an alias to another domain, it is must not be a host with
"A" records. You need to fix your DNS data.
