atName not getting picked up during autoconfig

I'm getting an error when viewing the output of a concurrent program.  I've figured out the issue is due to one node of my EBS 12.2.7 instance isn't using the atName parameter from the context file.  After running autoconfig, I'm ending up something like this in the tnsnames.ora file

FNDFS_APPLTOP_AT_server01=

        (DESCRIPTION=

            (ADDRESS_LIST=

                (ADDRESS=(PROTOCOL=tcp)(HOST=SERVER01.domain.com)(PORT=1600))

            )

            (CONNECT_DATA=

                (SID=FNDFS)

            )

        )

FNDFS_APPLTOP_devinstance=

        (DESCRIPTION=

            (ADDRESS_LIST=

                (ADDRESS=(PROTOCOL=tcp)(HOST=SERVER02.domain.com)(PORT=1600))

            )

            (CONNECT_DATA=

                (SID=FNDFS)

            )

        )

Since both nodes have the same value for atName (devinstance), I would expect it to look more like this:
