Error in symmetry

I am modeling a spherical Helmholtz resonator on Comsol so I can find the resonance frequency by changing some parameters. I am using the acoustic module. To simplify my model, I used the quarter of the sphere (because of symmetry). Then in the physics part I added symmetry and chose the specific boundaries. In this case the resonance frequency changed in a range of 10 Hz. It is not the same anymore. What can I do in this case? I can't find my error!
Thank you in advance
