P: Months in non-English configurations show in English

When I choose to import photos, by date, instead of having 2016/janvier 18 , I have 2016/january 18. Which was not the case before doing the update. No element of the "import" box have been translated. this is annoying, because i have to change everything by hand and it takes too much time...

I suggest that the date format to follow the system language selected in preferences.

for example in the book module (I'm using the French version of Lightroom) :
when I add a caption to a photo and I choose "Date" in the popup of the caption,the date appears in English like "31 January 2016" instead of in French "31 Janvier 2016"
Everything else is in French

Same problem with German language, even reinstalling 6.0 to 6.4 does not change anything, import destination stays in English.

Excellent, thanks.

Thanks for reporting it.
We are looking into this issue.

Thanks,
Sunil

I realize that the format of date en French was wrong.
The month should be in French when my software was installed in French!
See capture screen.

Thank you Chris... so it seems something went wrong using non-English languages, both in LR 6.4 and LR 2015.4 for Mac.... 
Hope to get a solution or a patch soon. Until then, I renamed my "month" folders to its english name, so new imports don't mess it all...

Same problem with my language Dutch. None of the suggested things works. Everything stays in English.... ( Mac OSX Yosemite -Lr 6.4)

Thank you. I had checked both things. Double-checked now, just in case. 

In Mac OS X everything is OK in the Language & Region preferences.

And I resetted LR preferences, did it again following the steps in your link. Also uninstalled and reinstalled LR. Nothing.

Happens the same on both my laptop (Macbook Air) and desktop (iMac). I think it is related to the new LR version... 😞

Two things to try:

1. LR relies on the regional preferences set in the operating system, and there have been a few users who have reported that those preferences got changed mysteriously.  Go to the OS X System Preferences > Language & Region.  Make sure the settings there are correct.  Then click Advanced in the lower-right corner.   Make sure that General > Format Language is correct, and then verify that the settings on the Dates and Times tabs are correct.

2. If that doesn't help, try resetting LR's preferences: http://www.lightroomforums.net/showthread.php?25197-Resetting-the-lightroom-preferences-file-updated. That often fixes things when LR's user interface goes wonky.
