Noob Question: Why is my PUTs performance not relating to the drop stock price?

https://imgur.com/a/kiEwmid You can see the above link I have PUTs on $SHLD with a strike price of $2. Why is my return line graph not increasing as the stock goes down? Shouldn't they directly linked? Thanks for any help understanding this.
