AbleCommerce Shopping Cart Software

I just realized the canonical link is messing up on my site. For some reason, it configures the page url twice. To see what I mean look at the source code from one of my pages:

<link rel="canonical" href="http://www.contractors-solutions.net/wo ... boots.aspx" />

This is causing a lot of errors in Webmasters tools.

I am using AC GoldR8 v. 7.0.88.7345

Why would it do this and how can it be corrected?

Thanks,

Scott Kahle
