[Plugin: SEO Internal Links] hyphenated words failing

this doesn’t seem to like hyphens. i have a long, long list of products that have hyphenated model names (ex: Awesome-2000). I have tried using quotes to group the term and that doesn’t seem to work either. It works great with single words, but not with anything hyphenated. how do i fix it? is there a function in seo-links.php that can be easily modified?
