docling doesn't see images in some docx files

Bug

I tried to take images from docx using docling but I found that in some files he did not see images and I don't know why.
...
My code(there are methods in my class):

    def _docling_parse(self):
        pipeline_options = PdfPipelineOptions()
        pipeline_options.images_scale = IMAGE_RESOLUTION_SCALE
        pipeline_options.generate_picture_images = True
        pipeline_options.generate_page_images = True

        return DocumentConverter(
                    format_options={
                        InputFormat.PDF: PdfFormatOption(pipeline_options=pipeline_options)
                    }
                )

    def _get_images(self, output_dir, document):
        res = []
        picture_counter = 0
        images_dir = output_dir / 'images'
        images_dir.mkdir(parents=True, exist_ok=True)
        for element, _level in document.iterate_items():
            if isinstance(element, PictureItem):
                picture_counter += 1
                element_image_filename = (
                    images_dir / f"{picture_counter}.png"
                )
                res.append(Path('images/') / f'{picture_counter}.png')
                with element_image_filename.open("wb") as fp:
                    element.get_image(document).save(fp, "PNG")
        return res
   def docx_parse(self, file_path, output_path='./'):

        input_doc_path = Path(file_path)
        output_dir = Path(output_path) / f"parsed_{input_doc_path.name}"

        doc_converter = self._docling_parse()
        conv_res = doc_converter.convert(input_doc_path)

        output_dir.mkdir(parents=True, exist_ok=True)

        images_list = self._get_images(output_dir, conv_res.document)

File that has incorrect conversion
