It's a FR24 error. The widebody appears as returning as IB3179, with the narrowbody as IB3167, but that isn't the case.
I think it's down to the callsigns having been swapped at some point (maybe because the sequence used to be IB3167/3179/3173, whereas it's now 3179/3167/3173). I've seen this happen a couple of years ago too.
