Date column translation problem

Hello everyone,

I have a question about Monday date column. I have enabled the “show day of the week” option.

It seems that until today, the day of the week was translated into my current language (French).

Now this day came back to the english translation value. Do you know if it is a regression or if it is something usual ?

I was used to use the french translated days so It would by annoying for me to come back to English.

Thank you for your help, have a nice day,
