If you use the Builder to generate the code then paste the code to the file functions.php, please re-type the name of the field. I’m going to discuss with the developer team to research and cover this case. Thank you.
Thank you for teaching me that it is difficult to treat tone accents as text.
I often use the process of creating complex custom fields in MB Builder and customizing them in PHP.
It was very difficult to manually enter the name, group title, add title...etc. field, so it would be helpful if we could generate a code that was ready to use as before.
