Problem: Routing Using Wild Cards

[eluser]Shiju S S[/eluser]
What I could figure out is that the router is stopping at

$route['([franchisee]+[a-z_]+)'] = 'franchiseearea/$1';

The last route in the second set. (Franchisee area)

ie:
When I give a URL
staffreport/showcontact
It is redirecting to
/franchiseearea/staff

All routes defined below:
$route['([franchisee]+[a-z_]+)'] = 'franchiseearea/$1';
is getting directed to it.
Any solution. I am also trying to gather more information.
