These CPR consist of two independent branches corresponding to $0-$ and $\\pi-$ states of the contact. We have found that depending on the transparency of the SIs tunnel barrier the decrease of the s-layer thickness leads to transformation of the CPR shape going in the two possible ways: either one of the branches exists only in discrete intervals of the phase difference $\\varphi$ or both branches are sinusoidal but differ in the magnitude of their critical currents.
