Hair Particles ignoring shape

My hair hair particles are rendering like big triangles or something? I am guessing that when rendering, Blender is ignoring the shape setting??? In the viewport it looks how I want ti. But when rendered, The hair is just big plane like triangles? I have rendered it before and it was fine. I don’t know if I changed a setting or something but now it wont render correctly.
I am using eevee. Yes I have set the hair render to “strip”

Can anyone help?

Thanks
