Odd problem with old attachments.
 

I noticed sometime back that old attachments wouldn't load when I tried to view them in the admin panel, but today after looking at it again, I notice the URL's aren't right either

I'm in the admin panel, attachment section, I click search, then "View oldest attachments"

None of the attachments work and several have the same post URL, which is

Anyone know why they have a really high post number?
