Hi @jknetdesign
Twenty Twelve is a very old theme, could you please try it on Twenty Sixteen instead? After that, could you please add the code to the template file and see if it returns the correct data? If it returns the correct data, then it has something to do with your theme. In this case, I suggest you get in touch with your theme author instead.
Also, could you please create staging/development site, open a new support ticket and provide temporary admin credentials to the staging site? 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.
That way, we could try to do some tests without affecting your live site.
Thanks 🙂
