No caption imported

Hi Katsushi, the plugin cannot import neither title nor caption, but interestingly, any other metadata work: %title% %credit% %camera% %caption% %created_timestamp% %copyright% %aperture% %shutter_speed% %iso% %focal_length% The page: https://codex.wordpress.org/Function_Reference/wp_read_image_metadata#Return%20Values says that a number of IPTC and EXIF fields may be used for %caption%, but no matter which I use, there is nothing shown by this plugin. (I tried -ExifIFD:ImageDescription and -ExifIFD:UserComment.) Note that the field ExifIFD:ImageDescription gets imported just fine with standard Media Library importer. Any idea? If you need more info or sample image, let me know please.
