Questions about caldera forms and popup-pro

I've made a form with caldera forms and made this form viewable in a pop-up pro (when u click on "reserveer" button on my site).

In the form I have those date fields, but they don't show the datepicker (see attachment) in popuppro. It does show when u want to see the example from form in Caldera...

My second question is, how can you get the "thank you for fillin in" screen after u click on send?

My last questions is, how you get the slugs (see attachment 2) in the send mail with the filled in fields. The slugs are the caracters I need to conclude the mail.

I've granted access. Glad to hear from u guys...
