[Pharo-project] Weird problem...having several "implementors" for the same method and class

Sorry, I know the subject of the mail is confusing, I am confused myself. Ok, I am doing hacky stuff and playing with CompiledMethod proxies, but I have a problem searching for implementors. So, I have for example CompiledMethodProxy >> mareaUninstall. But when I search for implementors of "mareaUninstall" in the popup of implementors it shows FOUR times, "CompiledMethodProxy >> mareaUninstall"... why ??? it should appear only once.. I attach an screenshot. Does anyone know what can be happening? thanks in advance, Mariano
