It was a mistake on our end not enabling the option that prevents your library from being autofilled on purchase. We’ve since enabled that option, but if you bought the bundle in the first 7 hours or so the you will have had all the games placed directly into your library.
Depending on how much of an issue is for some people, we may be able to provide a tool to remove all the games added so you can add them one at a time from your bundle’s purchase page.
