The non-harmonic tones are aliases. Do you understand about aliasing in
sampled signals?

I would think that the signal is already sampled, so they're not
aliases.

They still could be. If you perform a non-linear operation on a digital
signal, you introduce harmonics that can go past the Nyquist frequency,
and those get aliased.
