I can only assume that you implemented the code changes as well as friendly urls and now Google is re-indexing your site. So that can take quite some time.
In the meantime you will have a lot of duplication till it settles down.
It could take a very very long time.(Weeks,Months)
Unless possibly you resubmit a sitemap(Giz hack)
Probably something Giz and Id242 should have mentioned.
Was there something Giz or myself should have mentioned that did not get mentioned?
Driv's screenshot does not look like he has the "Better URL Sanitization for SEO" installed. He looks to be running stock code.
If Driv does choose to manually install this fix/solution, a complete write-up can be found @
