stress in poroelasticity gives irrational results - mesh problems?

Dear everybody,
I simulated a geothermal reservoir (cubic) which is stimulated by a "massflux" through a sphere. I think my model runs and works as it should.
I calculated the pressure and get results as expected. In comparison I calculated the maximum principal stress and get irrational results. In the same location near the sphere I get minimum and maximum results.
The support proposed to improve the mesh around the spheres. Do you have any idea how to handle this or is there another problem with the solid mecanics?
Attached you can find my model. As you notice I am a beginner in comsol.

Here is the model. I deleted all meshes and solutions to send the model.
