As a stop gap, create a folder with a completely unique name (like "My Copies" if one doesn't already exist). Now set that as the default Copies to self folder and see if it works.
If it does, copy any messages in the visible copies to self folders to the newly created one then delete the empty folder. Once done, restart Pegasus because you may see more. A side affect of duplicate folder names is that Pegasus may not be able to display them in the folder list. The restart will regenerate the folder list potentially displaying some that were not visible before.
Hopefully this process will allow you to remove all of the copies to self folders.
As a final check, make a copy of the HIERARCH.PM file, open it with a text editor and look for any entries that contain "copies to self", "copyself", or similar (ignore the 'My Copies' one created earlier). If any exist, you will want to record the filename associated with these entries. This what the entries look like:
0,0,"R0RMXURJ:1FD6:copyself","033F1989:My mailbox","Copies to self",0,20
0,0,"L523X8AV:43A9:FOL0048F","033F1989:My mailbox","Pegasus_Mercury related"
The content following the second colon is the filename of the pmm/pmi file pair.
With Pegasus Mail closed you would move these file pairs out of the mailbox directory and move them back one pair at a time starting Pegasus between each move. This should make them visible in the folder list allowing you to move any messages out of the folder before deleting the folder itself.
Once all clean, restore of the default copyself.pmm & .pmi files, set it as the default copies to self folder, move the messages from My Copies to it, delete the My Copies folder.
Remember that Pegasus Mail needs to be closed when manipulating .pmm/.pmi files.
