kmail folder sorting

In SuSE 9.2 kmail sorts some of the mail folders in the folder list window alphabetically and with a blue older icon, like in SuSE 9.1. The problem is that a number of other folders are lumped in with kmail's private folders like inbox/outbox, and they have the same blue folder icon but with a green arrow underneath it. Why does kmail arbitrarily decide not to sort some folders in with the rest of them? Is there a fix?
