OK, I see the confusion. Here is the short answer in which I grossly oversimplify. The field of two photons is different than the field of a single photon: it is bigger (at any given point). That's why we say classical fields are made of lots of photons.
The more involved and more correct answer is that the amplitude of the field does not have a definite value for a state with a definite number of photons. This is similar to how you can't know both the position and momentum of a particle at the same time in quantum mechanics. However, if you average the strength of the field (specifically the root-mean-square average), you will find that it gets bigger in states with more photons.
