8.1 Why doesn’t BCS-2 apply masks to all images?add section
If the images of a job are of different sizes, BCS-2 only accepts the masks when performing batch operations if they have been dragged over the smallest image. In all other cases, it is possible that BCS-2 does not carry out the “Pull Mask” action for all images of the job. A mask must not be larger than the associated image.
