Add calendar and add event option is in English after French language settings

Under IPM's configure section there are options too "Add calendar" and "Add event" but these should be in French after French user preferences settings
How can I fix this, will setting browser's primary language to French help or is the language not required to be in the browser at all?
I have pasted below screenshots of the sections this issue is occurring:
