I’ve tried adding your code to my functions.php file, added a field group to the post type and logged in as a user of ‘Transporter’ and I could see and edit the fields in that group. I did not set any location rules on the field group.
You’ll need to dig deeper, my test was on a site with a default WP theme and only ACF installed. Have you tried disabling other plugins and using a default theme?
