Kindly post all the images of your setup. Make sure to include all BCs, details, and graphics. Ansys employees can not exchange any files, but can only guide looking at the inline images.
Also, have you tried replacing cyclic symmetry with frictionless support? does that work well? In the image above, you are checking the total deformation at a node, which can be increasing. Check directional deformations, in the tangential direction and see if those are zero or near zero.
