Stacking after denoise suddenly stopped working

[daafuuk]

Im in the folder of the selected date only, and stacking is selected in the denoise menu pop up but suddenly my images are no longer stacking. Stacking is currently grayed out all together. Ive restarted my software and my computer. ive read on other questions it just started working one day, but i need this solved asap as time is sensitive. 

any help is super appreciated.

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
