Urgent: Fundraiser thank you page is incorrectly directing

Hi-

Once a donation is made user is being redirected to
http://greenwell.gatherwell.com/blog/greenfundraisers/fundraiser name]/thank-you/

Under settings the correct url for the thank you page is without the "blog"
http://greenwell.gatherwell.com/greenfundraisers/fundraiser name]/thank-you/

I don't know why the "blog" portion is showing up in the url as there was no additional customization, and there seems to be no way to fix/redirect to the correct thank you page.

Thanks,
Cynthia
