SUMMARY
photos configured for  'Sort Item by Creation Date' and 'Separate item by month' but not all the photos are grouping together in a unified month/yr grouping. Where the majority the picture are in the proper month (ie Aug 2024)  there might be a couple photos in one or more additional Aug 2024 grouping. These may be part of a series. IE picture 001, 002, 003, 005, 006, 007, 009, and 010 would be in one group; 004 would be in another group; and 008 would be in a third group.

This does not happen for all months. 

STEPS TO REPRODUCE
1.  Under View, click sort item by creation date
2. Under View, click group by month
3. 

OBSERVED RESULT
not all the photos of a specific month/year group in multiple groups.  Multiple groups of the same month are created with different images in each group

EXPECTED RESULT
All the photos of a specific month/year group together in a unified month.

I can't reproduce the problem here, but I know the cause of categories being duplicated.
There may not be valid date information on these images. Does anything change if you re-read the metadata from the August 2024 group images?
