Help 2D rope-rope collision goes through

[panda]

Hello I'm trying to stack two ropes on top of each other in 2D environment. I enabled both self-collision and surface-collision settings but ropes are still going through each other. What might be the cause of this problem?

Here is a video of the problem I am facing.
