  "abstract": "It is shown, that the energy dependence of the chiral based $\\bar{K}N$ potentials, responsible for the ocurence of two poles in the $I=0$ sector is the consequence of applying the on-shell factorization approximation [1]. When the dynamical equation is solved without this approximation, the $T$-matrix has only one pole in the region of the $\\Lambda(1405)$ resonance.",
