woo deposits and date

I read that the deposits from woocommerce were now integrated. They are not working though.

Also, all the tours I want to enter have a set date so I wanted to remove the date field. I found the code for the functions file and put them in my child theme but it is still showing.

//add_filter('tb_show_date_book', 'func_hide_date_book');
function func_hide_date_book($show) {
 $show = false;

 return $show;

Is there another code I need t use?
