Hi @rudtek
I’ve just tested your export file and the code is working correctly on my installation. Maybe there are settings that only available in your site environment. In this case, providing the credentials to your site would be the best thing to do.
Could you please open a new ticket and provide temporary admin credentials to your site? If you can create a staging/development site and provide the admin and FTP credentials to that site instead, that would be wonderful!.
You can open a new ticket here: https://support.advancedcustomfields.com/new-ticket. Also, please don’t forget to explain the issue again and provide the link to this thread.
Thanks 🙂
