Bundle 101. As stolen from the FAQ:

I created and completed a giveaway and the winner has marked it as recieved, but my contributor value isn't rising. Is there something wrong?

No, absolutely not. There're three reasons this might be happening. The first is simply solved by waiting. There is a delay of up to twenty minutes before your value changes and it will update shortly. The second is that single entry giveaways do not count towards your contribution value. Because they only got one entry, they are not considered as a raffle, but rather a direct gift. The other is due to having too many bundle games given away. Your contributor value will be locked until you submit further giveaways that are not from bundles and will continue to rise gradually until the full value has been reached. For more information on how values are calculated when bundle games are involved, please check this thread.
