NextGen Gallery - Gallery Pagination linking to blog, not next page

Working on a client site (www.VergeJewelry.com).

Using Myriad Theme.
Question regarding NextGen Gallery on their home page.

Where they have their 'custom jewelry' we have a 9-image NextGen Gallery based on tags. The pagination buttons underneath the gallery is linking to a blog post, not the correct sub-page. It appears that the blog post URL is somehow getting inserted right behind the main domain URL.

URL should be:
http://www.vergejewelry.com/nggallery/page/2

URL is:
http://www.vergejewelry.com/verge-diamonds-nautical-trunk-show-httpconta-cc1mwxsjh-2/nggallery/page/2

I have a test page set up with the exact same NextGen code and it is working:
http://www.vergejewelry.com/bar-jewelry/test/

I mentioned the Myriad theme because the front page is created and updated inside of the theme options pages, not via a direct 'home page'. Also, on the front page the gallery is inside of a column shortcode.

Please let me know what your thoughts are.

Thanks,
Jeff
