Permalink's changed on import of site

Howdy,

I used All in one WP Migration plugin to migrate a site.
On the destination site the permalinks have an extra directory "data" which was not on the source site.

http://skintherapystudio.com/skin-care-services-montana/ is now:
http://skintherapystudio.com/data/skin-care-services-montana/

Not sure how to remedy this as I've never seen this happen before.

Thanks in advance,
Casper
