Redirecting error

I’ve been trying to setup the plugin to redirect me from one to another page, but it won’t do it right.

Here’s my setup:
Source URL: /madplaner/mongolsk-oksekoed/
Target URL: /menu/mongolsk-oksekoed/

Screenshot: http://prntscr.com/dn3yek

This is the URL it goes to, if I use the Redirect: http://sundmadnu.dk/menu/mongolsk-oksekoed/menu/mongolsk-oksekoed

So for some reason it just adds the URL to the other URL.

Anyone help?
