Stack Skipping Photos

[rh8056]

I just discovered this and am pretty thrilled at what it can do!

I have a decent amount of older Nikon photos, shot in both JPEG and NEF. I ran the following immich-go command over my entire server, but it seems like it only stacked roughly 10% of the options. I targeted a specific day to try to figure out if there are other options I could add to improve the stacking:

 immich-go stack -k=APIKey -s=http://immich:2283 --manage-burst=Stack --date-range=2011-0
7-22 --log-level=DEBUG --manage-raw-jpeg=StackCoverJPG

However, I have files like these two that were not stacked:
/mnt/photo_albums/2011-07-22/NIK_1709.JPG
/mnt/photo_albums/2011-07-22/NIK_1709.NEF

The file dates are different, but so are another set that did stack (1707):

$ ls -all /mnt/photo_albums/2011-07-22/NIK_1709*
-rw-r--r--    1 nobody   nobody     1865228 Nov 24  2012 /mnt/photo_albums/2011-07-22/NIK_1709.JPG
-rw-r--r--    1 nobody   nobody     7609583 Apr 10  2012 /mnt/photo_albums/2011-07-22/NIK_1709.NEF
$ ls -all /mnt/photo_albums/2011-07-22/NIK_1707*
-rw-r--r--    1 nobody   nobody     2927149 Nov 24  2012 /mnt/photo_albums/2011-07-22/NIK_1707.JPG
-rw-r--r--    1 nobody   nobody     7874914 Apr 10  2012 /mnt/photo_albums/2011-07-22/NIK_1707.NEF

What else is involved in the stack options besides the names and locations? Is there some reason these wouldn't stack?

Only name and date of capture matter
You can check with exiftool what is the capture date embedded in the exif data
