AI Denoise is not creating stacks

Question

I selected 20-30 raw files and apply a batch enhancement. I did select the creat stack checkbox. However, once the enhancement is completed, none of the images have stacks in the develop module. I can see the enhanced .dng files in the directory. But they are not in LR somehow. If i hit denoise again - LR will create second .dng on disk, that also invisible in catalog.

If I try to import that created .dng manualy, it shows as "half transparent" (like for other files that already imported) and its timpossible to import that .dng. I edited a lot of images before and it works well, so likely its not about disk permissions or gpu settings (I setted gpu auto, off, manual and get same result)

I have latests

lr 14.0.1

and mac os 15.0.1 (m1) but I found the same issue on rediit that was posted 1y ago

please, help to fix

If Lightroom says that they cannot be stacked because they are in different folders, while you see them in the same folder if you open that folder on disk, then that is almost certainly the infamous 'Capitalization Error'.

Basically, what happens is that you have two different folders, one called ‘XXXX’ (or a combination of upper- and lower cast) and the other one called ‘xxxx’. In other words, the names are the same, except for the capitalisation of at least one letter. Because MacOS and Windows are case-insensitive, your OS sees those two folders as one and the same folder and so it deals with this without you even being aware of it. You will only see one single folder in the Mac Finder or Windows Explorer!!! But Lightroom is case-sensitive, so Lightroom does see two different folders. Here's how to fix it:

You look for photos in the Library Module, not in the Develop Module.

Expand all stacks. Try changing the sort order of your photos. Try turning off filters. Try looking in Lightroom Classic's "All Photographs".
