Corona discharge in COMSOL

Hello guys, I just started to learn COMSOL, and I found a weird thing that makes me confuse a lot. I was trying to simulate the plating on the cathode and checking the corona discharge. First, I made a cone structure and the current density seems reasonable.(Figure 1)
However, when I increase the height of surrounding, the concentrated current density on the tip just disappear and change to the edges. (Figure 2)
I think it might change but not like this. I used the axisymmetric model in this case, and it remains the same if I change to 2D or 3D models.
