Just as a rare possibility.
Pegasus uses a uniq name for folders in HIERARCH.PM file that is different than real name of folder.
Believe these are created randomly, so unlikely a new folder would be created with the same id, but have heard of people coping a folder pair to a new name, and thus those two folders would have same uniq ids.
VHELKLHO:5264:MAIN is example of the ID with first two being the id. Usually the Foldername starts with FOL0xxx. I use a program to rename my folders, and it changes ID in PMM/PMI pair.
Might want to check the name linked to the folder in question, and see the sizes it reports for the PMM and PMI file. Could also be a corrupted PMI file, and right clicking on it, and using check consistency to see if index problem.
Examining the HIERARCH.PM file to see if any folders have same key. Also, if you have folders in multiple locations, could be a copy has same id.
I also do regular 7z archives of my PMAIL directory with dates in names as backups, and use RSYNC to keep a copy on a secondary machine. Copy images to 3 other machines just to be safe. Luckily never need to use a backup, but have occassionally checked it to make sure they would work.
Good Luck.
