Mac OS Big Sur added additional: sent, junk and trash mail boxes?
OK, so I upgraded to Mac OS Big Sur. I have 4 email accounts and have a master "on my mac" mailbox for set messages, trash, draft, etc and under each master-mailbox is the sub mailboxes for each email account.
Upon upgrading to Big Sur, I still have the structure mentioned above, but, there has also been added an additional: sent junk and trash mailbox for each email account directly under "on my mac".
Questions:
1) Why have these additional ones been added?
2) Trying to delete them says it will delete the whole email account?
3) They cannot be moved into subfolders
4) They are duplicates of the mailboxes above and they are holding the same contents?
Any ideas out there?
