ADA4857 pspice Model

I am trying to use the ADA4857 to generate a circuit model of a state variable filter in order to compare with measured results.  In our implementation, we are using a single supply (+5V/0) on the ADA4857.  When using the pspice model of the ADA4857 in Microwave Office, the pspice model does not work with a negative supply the is greater than -0.9V.  Is there something in the pspice model that I can change that will allow the pspice model to work with the negative supply grounded?
