Why does the Mas90 ODBC Driver keep showing up in Sage Intelligence?

We are having a problem with report totals doubling because the 'Mas90 4.0 ODBC Driver'  driver keeps showing up as one of the connection types. 

Example - The Tenant Viewer looks similar to the following listings - 

TENANT,      CONNECTION TYPE,           DB SERVER,      DB CATALOG,   DB UID,               DB PSWD

MAS_AII,      ODBC Driver SQL Server,    APPSERVER,     MAS_AII,            MAS_Reports,     ************

MAS_RCS,   ODBC Driver SQL Server, APPSERVER,    MAS_RCS,         MAS_Reports,     *********** 

MAS_MPL,   ODBC Driver SQL Server, APPSERVER,    MAS_MPL,         MAS_Reports,     **********

MAS_AII,      MAS 90 4.0 ODBC Driver,     APPSERVER,    MAS_AII,            MAS_Reports,     *********

The last driver should not be included. Why is this happening? And what can we do to get rid of this issue?

Thanks, 

Terry
