Redirects ?

My main site is
http://www.captrichwittig.com/
But all additional pages seem to have the following:
http://www.captrichwittig.com/capt-rich-wittig-realty-3/xxx

The line capt-rich-wittig-realty-3 is added to each and every other page. This seems to screw up google site index or so it seems to me. Have I done something wrong? it would seem that the additional pages should just be the page added to the URL without that added second line ending with -3

Stupid I know.. doing my best.
