Giveaways Values

Hi all.

I have a question about the value of the giveaways.

I contributed with 2 games of Alan Wake, first was $30 and the second $15. When I check my profile says that the value of contribution is only $30.

After first Giveaway was closed I saw in my profile in the field "Value: $30". After de second was closed I see same value $30.

The second game does not count?

The winner checked it as received.

Edited
I asked because I bought the games separately, I did not buy in package.

Thanks.
