Hi: As you indicate, this is an unexpected difference. We will have to see the model or a stripped down version of it that still has the problem to see what the issue is. You can send it privately to me. Also, what operating system parser are you using? If you change the [IBIS_Ver] to 3.2, does the problem still exist with the latest parser?
