Two Spam Folders

I use AOL via Apple Mail. I have two separate Spam folders; one in “On My Mac” and the other in “AOL”.

Sometimes, spam goes to one spam folder, but not the other; I do not know what determines which spam is sent where.

As the Spam folder in “On My Mac” seems to be preferred by SS, I would like all spam to (only) go to that folder.

Have you suggestions re how I can make that happen?

AOL’s spam filter moves the spam that it finds to the Spam mailbox on the server. You can turn off AOL’s filter so that only SpamSieve is active. Then all the spam will go to the same place.
