Nicetime not rendering in Admin Dashboard and Pages

I’m not sure what might happen with the nicetime function but it doesn’t seems to work in my whole installation, either in the admin dashboard or in my pages. The date are rendering as below:
I left my config files such as site.yaml etc. untouched,
I dont know what may cause the problem and I dont remember when the problem occured first, but I feel like it is related to my languages (french).

Any idea?

Many thanks for your help

I think it is working, but the translation is not working. Did you disable “Language Translations” in the admin?
