Duplicate Canonical Link and Index,Follow

Hi,

When using Infinite SEO, pn any page that I have set to NOINDEX,NOFOLLOW I get duplicate entries in the page head as follows:

<meta name="robots" content="index,follow" /> (SET TO INDEX)
<link rel="canonical" target="_blank" href="http://www.xxxxx.com" />

Then further down I get:

<meta name="robots" content="noindex,nofollow" /> (SET TO NOINDEX)
<link rel="canonical" target="_blank" href="http://www.xxxxx.com" />

As I said, this only happens (a) on pages I set to NoIndex, and (b) When I use this plugin.

Please help!
Thanks
