Blogger Archive Issue

Blogger seems to be eating a big hunk of my posts in my archive.  I just clicked on July 2010 in my sidebar, and it only shows posts from this past week, leaving out everything before July 23.  That means I have six posts that readers have no way of viewing unless you happen to already know the individual post's url.  I can't figure out why it is doing this- I tried republishing a few of the missing posts, no luck.  I pulled up June's archive page, and it seems to be fine.  Any theories or suggestions?

My blog is at blog.lovemanythings.net if you want to poke around and see if it is doing the same thing to you!
