Character stucks when jump on the platform

Hello, i am trying to make 2d platformer behavior. With default setup character smoothly goes down when walks off ledges because of capsule collider. I check “Use Flat Base for Floor Checks” in CharacterMovementComponent. It’s lool like ok. But if I jump on ledge from some distance and angle then character stucks in platform and looses speed.
