Flexicontent 3.2 - Date format in category filter

Yes, in the category.
In my field used as filter in the category, i get this on a french site (see attachment).
I should have "Pour la période de Août 2017" in french...
In the field, i use "%M %Y" as format. I also search in the language files on all the site the string : i have the string in french in the Joomla french translation (general file) but it's not used.
As this is a field and a format string, that is maybe the reason...

So as my customers don't speak english, they will not accept the months in english in the front side...
Thanks for your help Georges

Back for this question : how can i do this ? Do i have to edit the php file ?

Hello

i think i know how to fix the select drop down

You mean translate when showing date filter as
Year-Month (nnn)
In a select drop down ?

but i think you have not answer me are you using select drop down
or date picker input field ?

I use a dropdown in the search form and a date picker in the admin form.
To avoid misunderstanding (english..), i took some screenshots
Search form in front

Field in fields management

Content in admin


Thanks
