Default spell language

i’m using CODE (docker) with Moodle and the Collabora plugin. We noticed that the default spell check language is set to english on writer but french on calc and impress

how can we set globally the default language ?

I also noticed that the interface language is not completely translated on this new version

thank you

The interface translation is going to be fixed with with the next update.

I don’t know where the Moodle plugin is pulling their default files, would be best to check and adjust that.
Maybe it’s this, but I’m not sure, because as far as I can see these all have English language set by default:
