ImageMetadataReader.readMetadata(file) is missing data

Question

I have a single tiff file with multiple images inside. I want to extract the Image Description value for each of the images. I'm not sure why, but when I use ImageMetaDataReader, it's only returning the first and last Image Description. I have verified the data is there using exiftool and dumping to a xml tree. Any suggestions why this isn't working?

Metadata metadata = ImageMetadataReader.readMetadata(createInputFile());
            for (Directory directory : metadata.getDirectories())
            {
                for (Tag tag : directory.getTags())
                {
                        fileWriter.write(String.format(tag + "%n"));
                }
            }

If you want to retrieve metaData from the image in the Android project. Then you can do that with the help of https://github.com/drewnoakes/metadata-extractor implement this in your Gradle using implementation 'com.drewnoakes:metadata-extractor:2.12.0'

Complete code is as follows

private static String getImageMetaData(Uri image1) {

    try {
        InputStream inputStream = FILE_CONTEXT.getContentResolver().openInputStream(image1);
        try {
            image1.getEncodedUserInfo();
            Metadata metadata = ImageMetadataReader.readMetadata(inputStream);
            for (Directory directory1 : metadata.getDirectories()) {
                if (directory1.getName().equals("Exif IFD0")) {
                    for (Tag tag : directory1.getTags()) {
                        if (tag.getTagName().equals("Date/Time")) {
                            return tag.getDescription();
                        }
                    }
                }
            }
        } catch (ImageProcessingException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }
    return null;
}
