This seems to work quite well, except that the collection field when copying a book to the e-reader is now filled with: author (language) (author_lang), i.s.o. only author (language).

Any ideas how I can get rid of the trailing (author_lang)?

Yes... I believe it's default behaviour to have the name of a custom column in brackets when creating the Collection name. I don't think the same is true for a calibre standard column (e.g. tags or authors).

You need to visit Prefs - Tweaks and from the Tweaks list down the left-hand side find the one called Specify renaming rules for SONY collections. Then read the Help notes in the top panel (it's v-e-r-y l-o-n-g and detailed). I believe it exists for those who want to combine several categories into one Collection, or who want to create several different Collections and know which is which.

This is not a Tweak I use myself, but I think you may get what you want if you change the default

sony_collection_name_template = '{value}{category:| (|)}'

to

sony_collection_name_template = '{value}'

but you'll need to 'read and inwardly digest' in case I've got it wrong
