why does this only partially work? su enable-media-replace

i use enable-media-replace on my site. when i replace an image (after a zen-cache clear), the image updates in the media libray and on a page it’s used on.

but… the image doesn’t update in the slider i’ve created with shortcodes-ultimate. in shortcodes-ulitmate i’m calling the image using the image ID. the image id matches the new image in the media library but the slider still shows the old image.

how come?

eta: i even went so far as to edit out the image ID from the slider shortcode, save, reload, verify the image wasn’t in the slider, and then replace the ID into the shortcode, save, reload and it’s still the old image in the slider.
