Hi.,
Get into the file path /wp-content/plugins/simple-booking-manager/vc/shortcodes/ and replace the person_item.php file using the blow file ,
File : https://www.dropbox.com/s/852f775kvz6fnc7/person_item.php?dl=0
Now , you can use our person module to display those details – http://prntscr.com/ms5sba . It will display the custom fields values like the screenshot – http://prntscr.com/ms5qvf , http://prntscr.com/ms5qxr
We will fix this issue in our next update .
