In [1], we claimed that the correction to the gravitational energy flux, i.e. the energy flux from binary inspirals induced by the metric perturbation in dynamical Chern-Simons (dCS) gravity, enters at second post-Newtonian (2PN) order. Here, we point out that there are terms that we overlooked, and if we take these terms into account properly, the 2PN terms cancel and the correction enters at 3PN order. First, let us remind ourselves what we did in [1]. Our starting point was perturbing the metric around a flat background as
