Just noticed mine is set to "English"
I thought I had it set to "English (Australia)" but that option is not available in calibre 7.4, nor is "English (UK)". So I had a look in my Portable Version 6.last, not there either. But it is in my Portable Version 5.last.
Should I assume the translations have been discarded. Doesn't make a material difference, the translations had a number of omissions that jarred anyway.
