@Wolfspyder Can you restart Steam and add the bundle to your cart again to see if something has changed? The product team made a minor change to see if this solves the problem but unfortunately Steam doesn't allow major changes during sales so if it ain't solved we may not be able to fix it at the moment ><.

Unfortunately it's the way this bundle works and we can't give out keys for the upgrade pack as each key actually costs us money ><. The product team is aware of this issue and will see if something can be done in the future (as this is also related to Steam settings) but for now there's nothing for us to do.
