Spice Model for OP-400A

I am using Pspice to simulate a simple unity gain circuit based on OP-400 A. Schematic below. 

When I use any of the OP-400 A/E/F/G/H I see that there is a spike at the +V and -V pins whereas when I use OP-400 model I do not see it . Wondering if there is something wrong I am doing when using OP-400A or is there a newer model?

Thank you
