Appointments + : Set-up issues

Hello,

I just installed Appointments + on my website and I`m trying to do a custom implementation on my homepage by using only the plugin shortcodes.

So far I’ve encountered three issues:

1. the “next week” button appears when adding the [app_pagination] shortcode, but when clicked, it does nothing.

2. confirmation button appears when adding [app_confirmation] shortcode, but not the fields for name, email and telephone.

3. I would like to change the language for all the text appearing in the app, not just the ones provided in the arguments. Should I do a direct edit on the plugin files?

Really great plugin by the way and thanks in advance for your support!
