Narmer Shawzin suddenly sounds different

[(XBOX)Faunavir]

I recently bought the narmer shawzin, and it sounded smooth, not exactly sure which shawzin to compare it to. After changing my warframe, it suddenly sounds like an electric guitar. Nothing I do can fix this, and im not even sure if its a bug. And I wasnt messing with my settings before it changed.

Edit: Alright, figured it out. The game got confused when I bought it, and it gave me the dax shawzin instead. Then now its figured itself out. Im still keeping this up, because its still a bug. And also, the shawzins should have descriptions as to what they actually sound like. Would be VERY useful.
