Hi @creaturmedia
Jursdotme fixed his issue by updating his ACF to the latest version. Could you please try it too? If you already have the latest version, could you please re-download and re-install it? For the PRO version, you can get it from https://www.advancedcustomfields.com/my-account/, and for the free version, you can get it from https://wordpress.org/plugins/advanced-custom-fields/.
Thanks 🙂
