Names not being displayed in taxonomy tag admin

I’m using a taxonomy called “tidningar”, and the names of the items saved in the taxonomy are not being displayed in the admin pages, like so: https://s18.postimage.org/e87f2kog9/Sk_rmavbild_2012_05_23_kl_10_58_02.png

I know that they are there, since they are being displayed correctly in the sidebar when I’m adding/editing a post, they are just not showing up in the tag admin page. The number of pages each tag is being used in is not shown either, but the description is being displayed properly.

The relevant code in functions.php can be found here.
