IMHO when Calibre finds optimal matching, it merges all information into one large entry.
Note the "See at" entry on the right side of your screenshots: - When found it on Google, we see that it's Google.
- When found it on Amazon, we see that it's Amazon.
- When found in Goodreads, we can see that all information has been merged.
See hint for the main options when fetching metadata. |

I think what is happening is that when you have just Google and Amazon active, there is not enough information to merge the results. The authors do not match. But, when Goodreads is added, the Goodreads and Google are merged because they have the same ISBN. Then, the Amazon is merged because there is an exact title and author match with the Goodreads result.
That's my guess. I have never looked at the merge algorithm to see what it does, but, the above makes sense with the results you are seeing. I have at times wanted a "no merge" option. But, I have also wanted a way to pick parts of the metadata from the different results. Especially the comment, as the comments in the merged aren't always the best.
I don't think the option @BeckyEbook will have a real effect on this. That is about what happens if the source returns multiple books. With that option on, you could see multiple entries if the source finds multiple good matches. But, if identifiers are used, in this case, Goodreads, Google and the ISBN, there should only be one match for each source.

Thanks to both BeckyEbook and davidfor!
This is fascinating stuff the deeper you dig in to it. I'll keep playing with this as I now have a better understanding. And apologies for the poor formatting on the last posts, I'm figuring that out too now. Cheers!
