Calibre and Kindle Fire not showing new books

Hi
Quick question, I have a Kindle Keyboard and a Kindle Fire HD. When I plug the keyboard in it detects any new books I have downloaded from Amazon.

However when I plug the Fire in it just shows existing books in the library and not any new books.

I checked the settings but I don’t see anything obvious can any help fix this?

Also slightly lesser question on the keyboard when I send a book it also sends a file that gives me page numbers, can the fire also get this file to show page numbers?

Thanks for the help and advice
