I like to add the book series infomation in the metadata on Calibre (series name + number). However I'm having issues getting it across to my Kindle when the book has already been added originally without this metadata. Like these examples:

Sometimes I come across older books in my Calibre library (books which are already on my Kindle) where I have not added the series information. So I add the series metadata on Calibre, connect my Kindle and choose "device" and "update cached metadata on device". But the series information does not appear on the Kindle no matter what I do.

Or if I have accidentally already sent a new book across to my Kindle using Calibre and then noticed that I have forgotten to add the series information in the metadata. I go to Calibre, add the info in the metadata fields and choose "device" and "update cached metadata on device". But the series information does not come across.

I have even tried removing the existing book from the Kindle (with the series info missing) BEFORE sending the updated book (with the series metadata added) across to the Kindle and it still does not come across. So even though the book is gone from the Kindle, it's like it still knows it was there without series metadata orginally and therefore comes across without it again.

I don't know what I'm missing but surely you can somehow get across the series metadata added in Calibre to the books (already) on your Kindle which are missing it? Hoping someone can help me please?

Thanks in advance.
