align_image_stack works by default only on pairs of consecutive images (this can be changed by switch --align-to-first). For focus stacking the images should be supplied sorted by focus distance on the command line and you should add the switch --use-given-order. By default align_image_stack sorts the images by exposure values and compares so only images with least exposure difference. But for focus stacking this is not the best approach - in this case disable the sorting with --use-given-order (then align_image_stack uses the order as given on the command line). Now align_image_stack should only compare images with the small focus distance changes.
