Remove the English translation of books for other languages

Hello, 

Is it possible to remove the English translation of the books title from pages in other languages?

For example, here a French book is translated into English in the FR version, which doesn't really make sense : https://fr.numista.com/literature/volume.php?id=2028

Another solution might be to allow titles to be translated into all other languages, not just English.

Also, for book or magazine series, can you display the original title?
I completely understand the need to have a field to translate the title into English, but I think the original title should be displayed first.
