Strange ghost link

I have a strange ghost link that is showing up on my pages.

I’m using the following code in a loop:

<td><a href="[field url custom=true]" target="_blank">[field name]<a/>[if field=local_url]&nbsp;(<a href="[field local_url]" target="_blank">local</a>)[/if]</td>

The idea is that I’m linking to a page offsite, and sometimes I have a local copy of that linked page ion my site. In the case that there is a local copy, I simply display the text (local) after the actual link, with the word local linking to the local copy.

What’s weird is that the opening parenthesis is showing up as a link. It’s a separate link for the word local, and it’s a blank link (it doesn’t go anywhere).

Anyone see a problem in my code that is causing this ghost link to show up?

Thanks.
