Series Not Connecting

[Megan]

I'm seeking help connecting the four books in The Tale of Bryant Adams series. I've gone into the book pages to look for errors and can't figure out where I've gone wrong.
The first two books are linked here: https://www.goodreads.com/series/1982...

Book three: https://www.goodreads.com/book/show/5...

Book four: https://www.goodreads.com/book/show/5...

If you could please let me know what I did wrong so I can look out for the error in the future that would be much appreciated.
Thank you for your help,
Megan
