Contact interface issue on Creo Simulate 6

I am using Creo Simulate Release 6.0 and Datecode6.0.4.0

A contact interface with infinite friction on a pin allows material compenetration and gives skewed deformation results. I tried switching from component-component to surface-surface but reached the same results. The issue happens on a particular pin in a specific location, so I tried to delete and re-create the interface but no changes. The geometry is correctly highlighted in yellow on "review geometry" and the mesh completes without problems. Any Ideas on why it is happening?
