The web page links to a journal article that you have to pay for, but you can find the freely-readable version of the full article at https://arxiv.org/abs/1802.08257 . Section 4.2 discusses dust emission. The original paper they're correcting is at https://arxiv.org/abs/1711.00578 (section 3.2). This paper concludes that the previous paper had wrong assumptions because a flare happened during their measurement, so they didn't need to hypothesize that there is a dust belt (at least the 2 inner ones; they didn't have info about the far outer belt) to account for the supposed "excess emission".
