MPIO error - Dell PE 610 server with MD3200i storage

I am trying to configure MPIO round robin on our system but get an error that says Incorrect Parameter and then it remains at Least queue depth.

On this server we have two IP addresses.

Server                                                              MD Storage

Nic 1 192.168.130.10                               192.168.130.101

Nic 2 192.168.130.11                               192.168.130.102

I can see both target ips when I run the iSCSI initiator but just cant set it to round robin for some reason. When I click devices then MPIO and try to add the second ip address I get the error of "incorrect parameter"

Does anyone have an idea or can point me in the right direction. I have tried following the MS instructions to no avail.

thanks

Marc
