Narrative:
Aircraft Y and aircraft X were both going to bwi. These aircraft were rerouted by tmu via kelln Q58 peett thhmp RAVNN6 bwi. The problem is that they entered it into the machine as 'kelln..Q58..peett' (using two dots between these entries). There is a seaplane base named crooked lake in angola; indiana. The identifier for crooked lake is 'Q58'. Eram (enroute automation modernization) believed that these aircraft were not flying the 'airway' but to the seaplane base Q58. This creates two different problems. First; the conflict probe was not working as we believed because eram thought the aircraft was on a different route after kelln. Also; if a controller ever clears an aircraft via 'kelln Q58 peett' then we are not sure if the pilot will put in the airway or the fix. Having two fixes/routes with the same identifier is a safety issue. Either renumber Q58 to a number that does not also have an airport with the same identifier or change the crooked lake to a different identifier. In the meantime; brief all controllers (including clearance delivery of any tower) of this possibility so they can ensure that the pilot accepts the correct routing.
