This problem disappeared for me after I checked "Delete after N Days" checkbox, and set N to something short, like 1. Before, I had neither that nor "Leave messages on server" checked. This might be a normal behaviour thus, but confusing, as one would normally expect that setup to delete messages immediately.

I'll update the upstream bug too.
