Hi Antonio,
Thank you for the reminder, unfortunately a lot of data was lost on our server, still our host was not able to tell why.
I see the centering issue was fixed already, so the remaning is the date. I am not exactly sure if that was possible. You can create a date filter actually on custom fields, I believe that is as close as it can get: https://documentation.ajaxsearchpro.com/frontend-search-settings/custom-field-selectors
