I did not recieved the contributor value?

Bundle games. I recommend you reading the FAQ.

Here

Edit: Beaten to it.

I think the reason for that is that Shank 2 is a bundle game and you already gave a lot of bundle games away.

Games which have been in bundles or otherwise made widely available at little or no cost are added to the bundle list. Games in this list will not add more than 20% (1/5) of your non-bundle contributions, disregarding the first $25. For more detailed information, see this thread.

In order to receive any additional value from your current bundle gifts, partial or otherwise, you will need to contribute more in non-bundle games.
