Some Permalinks Working, Some Are Not

Hello –

Some of my permalinks are working and some are not, and I can’t figure out what the problem is.

If you go here: http://www.mlqattorneyservices.com/blog/ you will see that when you click on the first two posts, they are screwed up, but every post after the first two are fine when you click on them to read them in full.

What’s going on?

Thanks in advance for any help!
