MPC VST in Cubase, not loading right programs

Here’s what’s happening:

I instantiate MPC as VST in Cubase and I load Program A in Cubase Session A the. save the session.

I instantiate MPC as VST in Cubase, load Program B and save Cubase Session B.

When I load Cubase Session A, the instance of MPC VST loads Program B instead of Program A.

Does anybody else experience this or know a way to force MPC VST to the session specific program, not the last loaded program?
