    when using contacts, specially N2S contacts, the contact pairing identification depends on the selection of who is the master and the slave. Usually, the master is set as the coarser mesh, and slaves are more refined, so that many slave nodes can be found by the master side.

    Probably you need to refine your mesh a little bit better, specially in the contact zones, to get a better pairing.
