Language Support for Pages Associated with Action Blocks

- I would like to be able to change the langage of the RSVP date and location into French for example:

I send an email in French and add the RSVP option in French but "Date" and "Location" appears in English and can't be changed.

- I would like to customize the time of my event with 15' and 45'. For example:

My event takes place from 12.45 to 1.45 but the tool doens't provide me with 45 (only 00 and 30).

- Accent in other langages like é in French appears as symbol or error in the final email which is received by the recipients.
