We study multiphoton ionization of Kr atoms by circular 400-nm laser fields and probe its photoelectron circular dichroism with the weak corotating and counterrotating circular fields at 800 nm. The unusual momentum- and energy-resolved photoelectron circular dichroisms from the ^2P_1/2 ionic state are observed as compared with those from ^2P_3/2 ionic state. We identify an anomalous ionization enhancement at sidebands related to the ^2P_1/2 ionic state on photoelectron momentum distribution when switching the relative helicity of
