Using Cylindrical Coordinate in Electrostatics

Hi I'm trying to simulate the electric field on the top surface of a piece of diamond by placing two electrodes (a round electrode in the center and a ring electrode on the outer part) on top of it. I'm interested in the donut shaped area between the electrodes and I want to view the results under the cyclindrical coordinate. I've tried selecting the default cylindrical coordinate under the charge consevation node of the Electrodatics module but somehow the coordinate could not be successfully applied. I've also tried manually setting up the coordinate system using the base-vector node (see attached plot), but it didn't work either. I've attached the result below for es.Ex. Could anyone help me figure out what is wrong here?
