Title problem after installing Query Multiple Taxonomies

I am using several taxonomies on my site and after installing Query Multiple Taxonomies for search purpose, I have noted that it adds taxonomy term in all page titles.

For example title of my this page was http://www.wikivisas.com/courses/country/newzealand/
New Zealand : Wikivisas

and after installing, it is;

country: New Zealand : Wikivisas

I want to remove this.
