CSI for Powermax Port Group creatation and naming

We provided an existing PG name as part of input parameters and verified the name matched an existing PG on the PowerMax but CSI went ahead and created its own PG anyway.

We are using CSI for PowerMax 1.5

- name: X_CSI_POWERMAX_PORTGROUPS value: PG5-Eng1-2

But created:

csi-DEV-FA-4D-9-FA-2D-9-FA-3D-9-FA-1D-9-PG

The purpose of supplying an input PG is for CSI to use that PG name right? I don't find anything in the log specific to CSI creating the PG. 

Is there a way we can have CSI use the PG name that is supplied in the Parameters?
