oddness in the archives

hello,
i used a script a while back to transfer my MT enties to wordpress. it worked for most of them, but didn’t for others. if you look under the archive area of my site, you’ll see months, and then “12 10 9 2 1”. the links don’t work. i *did* make a backup of my import.txt, so i do have those entries. the problem is, i can’t seem to figure out how to remove those archived-files (the numbers). i can’t do it from the admin panel. is there a way i can do it from phpmyadmin (by editing the queries)? it’s just so tacky, lol. i want it gone! ??

thanks so much, i appreciate any suggestions.
