Another Problem With PulpFiction

Ok, maybe I’m not using the program the way it’s supposed to be used. Here’s what I’m doing. I’ve subscribed to all the feeds I want. PulpFiction automatically checks for new posts every 30 minutes. They are downloaded to the Inbox on my machine. I read the posts and the ones I don’t want to keep, I delete by hitting the delete key. For some reason though, I those same posts that I’ve read and deleted are sometimes re-downloaded a few hours or even a day later. It’s very strange. It’s not the end of the world. But it’s a bit annoying.
