EVAL-ADG2188EB giving weird results

I attached my newly received eval board to my PC via the USB.

I can set/unset the connections just fine but the results are confusing.

If I measure between i.e. X0 and Y0 and then mark it for connection in the software and say update, then I see that the ohmmeter goes from Overload to some flickering value around 120-140kOhm.

If I toggle all on it drops to around 40 Ohm.

I can see that the more I toggle on the lower the value gets. And I've tried a various combinations of connections with the same result.

Any idea?
