Divisors@5 = {1,5}
DivisorSigma[1,5] should returns sum of this list and everything is ok because DivisorSigma[1,5]=6.

I have problem with Gaussian Integer
Divisors[5, GaussianIntegers -> True] = {1, 1 + 2i, 2 + i, 5}
DivisorSigma[1, 5, GaussianIntegers -> True] IMO should return 9 + 3i, but return 4 + 8i. But why this strange result?
