Setting calendar parameters on a Bookings reservation page

Hello everyone,

I've created a booking page for my company to allow people to make appointments with specific people within the organisation for specific services.

Everything is set up correctly, except for the calendars, with which I've encountered 3 problems:

1. Although I had selected a 30-minute interval between appointments, some booking times were only 5 minutes apart.

2. I have selected the French language in the page settings, but the appointment times still appear in AM and PM.

3. I've set the personalised availability times to between 9am and 5pm, both for the services and for the employees concerned, but the booking page still allows you to make an appointment after that.

If anyone can give me a hand it would be really nice, I'm struggling...
