The release process of Batch Job will be completed only when all images are released properly. In multi-image output process, the images are output in the order of the first image, the second image, and the third image. The first image is output when there is no file with the same name. This duplication checking is performed for every image. The confirmation message for overwriting appears in the middle of outputting if there is a duplicated file. If you refuse to overwrite at that time, file output will be canceled and release process will not been completed, yet the outputting file will remain as it is. When the above phenomenon occurs, check the destination directory of releasing and make sure that the release file name is unique.
