Answer: When an image is added within FSF it is not assigned an order ID by default. This means for example, if you added 10 images and then only ordered five of these images without ordering the remaining five the remaining images would not conform to a sort order during the output of the fact sheets. This is bug within all versions prior to v1.0.6. To correct the problem and ensure the sort order, sort all images within the set, even if they already "appear" to be in the correct order. Or use the Sort Ascending function and then sort the images to the desired order.
