When the form first appears, it picks up the old Diva rules from within the library. Some Diva rules can be run with Assura - but not all - they sometimes need some modification. Given that this PDK has Assura rules delivered with it, it's better to use those. However, you need to pick them up by specifying the technology choice:

The choices will come from the assura_tech.lib - which then would set choices for the Rule Set. If I use this cyclic field and pick gpdk180, I then get:

So then you can see it's pointing at the Assura rules rather than the Diva rules. Once you've run one LVS with this setup, it would remember that in the last state information for this working directory (or you could use Save State at the bottom of the form).
