Should this really be combined?

It contains extra content that the other books don't have. How different, revised, does a book need to be to not be combined?

Doesn't look like that qualifies to be a separate book. Less than 5% added, it appears. That usually means slight changes, or a bonus short, or something like that.

Okay. Didn't know how different they need to be. Thanks

Pretty different.
