 Did system maintenance result in enablement of IMS management of ACBs?

Attempting to start our IMS region after the last round of maintenance is resulting in:

DFS3505E ACBMGMT=CATALOG AND CATALOG=Y IS REQUIRED IN PROCLIB MEMBER=DFSDF000, JOBNAME=IMS15CR1 IVP1

According to the message information:

If the message text states that ACBMGMT=CATALOG and CATALOG=Y are required in the PROCLIB member, IMS management of ACBs was enabled, and either ACBMGMT=CATALOG or CATALOG=Y was not specified.

System programmer response = Correct the PROCLIB member definition, and try IMS initialization again.

We've tried updating the configurations in member DFSDF000 without success.

Was IMS management of ACBs enabled during maintenance, how do we resolve this?
