[Plugin: Link Library] Links in Notes section have domain appended

When I use the notes section and add an href as part of the note, the link produced has my domain added to the front:

http://www.mydomain.com/linkcategory/www.thelink.com

It’s not happening on ALL links, just some. The href syntax in the note section for the ones with the domain appended is the same as the ones that are fine!

Any ideas? I’m stumped.
