Issue in isResource having same words in URL

[amitmeghare]

I have two URLs

http://127.0.0.1:8000/roles Nav::isResource('roles')
http://127.0.0.1:8000/roles-assignment Nav::isResource('roles-assignment')

But when I am on the roles-assignment URL the Nav::isResource('roles') also return active.

How to resolve this permanently?
