Moved pages don't update URL of change

Permalink
Hi all,

I am sure there is a simple explanation for this but I am at a loss. My client has created some pages, put them in a sub-folder and then moved them to a new sub-folder (or renamed that sub-folder), now the URL doesn't reflect the change meaning that pages are appear in the wrong drop-down menu.

Structure:
- Home
- About WRC
    - Page 1
    - Page 2
    - Page 3
- Other
- Contact


Page 1 used to be in a sub-folder called 'Administration' but was then moved to the 'About WRC' folder but 'Page 1' still has the URL of /administration/page-1/ as opposed to /about-wrc/page-1/

Is there anyway of forcing Concrete5 of rescan that URL's? I have re-run all the options in 'Scheduled Jobs' with no luck.

Any help would be greatly appreciated.
