I know that the system generates 4 sound tracks once the sync is done and I will have to keep 2 tracks but I am not sure if the robotic sound is related to this.
I think I'm not quite following (not unusual). To clarify: You have 4 tracks in your merged clip and you're going to retain 2 of them? Are these 4 tracks from the camera mic and your external source?
How did you sync?

OK. Then I would think you'll want to discard the onboard mic tracks before merging – or disabling them – or not merging at all. But your report of an echo seems to indicate that your sync is off by a hair, so you might want to inspect those clap wave forms very closely.
If you haven't already done this, check out Plural Eyes @ Red Giant. Great product for FCP. I think it's $100, but they have a trial version. (Finally, FCPX also has a trial version and its syncing feature appears to be pretty solid.)

If you no longer need the camera audio and your sync is good, in the Time Line option click on the tracks you want to discard and then delete.
Or select and delink (command L) audio, delete the camera audio then relink the remaining tracks.
If you didn't want to delete you could also disable the entire tracks by pressing the audible icons on the left of the TL or selected clips by delinking and disabling (control B).
