At first, I have the German amazon server as the download source.
calibre version 5.35, Windows 10 Pro (21H2)

For example ISBN 3499275120:
If I use the identifiers 'amazon_de' or 'isbn' for downloading the metadata, there is no series and releasedate information. All other seems good.
If I use 'amazon' as the identifier, it loads series and release data. There is no description text, because it uses scrapes from amazon.com site.

The same for the kindle format of this book (B07CMQGRMD):
If I use 'amazon_de' as identifier, there is again no series and releasedate data.
The other two identifiers don't work here.
