CST - How to fix this cylinder insertion problem in CST 2023?

Hi,

I have started designing a conformal patch antenna , which has substrate material along the whole cylinder,another layer of the cylinder is antenna ground PEC.   when I am trying to make the coaxial cable for the conformal antenna it shows that some parts of the ground plane already intersect with the substrate layer of the cylinder, therefore probe is getting shorted gives so many ripples in s11 with bad matching above -10 dB.  By default ground plane is intersects with the substrate in some parts of the cylinder. Can anybody please fix my model's coaxial probe so that it can't intersect with ground?
