A category was moved and it created a new url so we had to create a 301 redirect in htaccess for the old url to the new one however the redirect is not working fully.

The old url is http://www.worklinesafety.co.uk/safe...ts-c-6_32.html and the new one is http://www.worklinesafety.co.uk/safe...-6_119_32.html

we placed in the htaccess the following code:
Code:
Redirect 301 /safety-footwear-rigger-boots-c-6_32.html http://www.worklinesafety.co.uk/safe...-6_119_32.html
The redirect does cause a redirect however it loads as http://www.worklinesafety.co.uk/safe...ts-c-6_32.html As you can see the url is missing _119 Category ID.

We use the Ultimate SEO URL plugin.

We do have a few other 301 redirects that work 100% however we cannot figure this out.
Code:
Here is our full htaccess code incase there are any conflicts happening:
