I'm not too sure. Do you have some sort of EXIF data extraction software installed on your PC like Exif wMarker or something to check that the information is being added.
You can also use an online service from a PC or Phone and upload a photo to a site that will read the information and display it for you. Get EXIF Info: Extract and View EXIF Data from Images
You can also install EXIF viewers for your Browser Google Chrome
