new posts displaying after old

My site: http://www.krystallarsen.com/blog

You can see if you scroll down there are two new posts (“so sore,” “movie review – defying gravity”) that were written after the posts that are displaying above them. I’ve tried changing the publish dates of these posts so they appear to have been published even sooner – to no avail. The publish dates of these posts is after the ones displaying above, yet they continue to display after as if they are older posts.

It only just started doing this today – I’m in the process of reposting all my entries after some site issues that necessitated a reinstall so I’ve posting many posts a day. Please help ASAP. Thanks.
