Change the language of fields in Microsoft Word
Right-click the field and select "Change field..." (or whatever the item is called in your language of Word).
In my case, the field is BIBLIOGRAPHY \l 1053
. 1053 is the Microsoft Locale ID (LCID) for Sweden. I just changed it to BIBLIOGRAPHY \l 2057
, where 2057 is the LCID for English - United Kingdom.
Then the bibliography changed language, so there is no more "Fifth upplagan" instead of "Fifth edition"!
Reference:
- Locale IDs Assigned by Microsoft
You can also just delete the language code in the field, then the bibliography will update with the language of the rest of the document
