Do you know why I do not get as many points as contributions?

I do not understand what you're trying to say. Repeat it, in a more understandable way, please.

it's part of a bundle

Bundle games only raise your contributor value to $30.

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.
