Angular 1/ui-router – stateMatcher.find error

When navigating a component I have a series of stateMatcher.find errors

stateMatcher.find: Found multiple matches for agent.project.detail using glob:  (2) ["agent.**", "agent.project.**"]

being on the state headquarter.project.detail but 2 states (agent.project.detail andheadquarter.project.detail) use the same component

What do these errors mean and how can they be avoided?
