Non Linear Analysis- Material S-S curve

Hello Solidworks community,

I am doing a non linear static analysis for a simple part  and I want to include material plastic curve. Here is my input  S-S values, but it keeps giving me the error shown below, I know the first point has to be yield point and non-zero. I have also tried using default solidworks material card (Very low density PE (SS)) and the error doesn't go away. What am I missing? Thanks in advance
