  The authors of ref. Phys.Rev. D94 (2016) no.1, 014502 reported about a
careful analysis of the impact of lattice artifacts on the $SU(3)$ gauge-field
propagators. In particular, they found that the low-momentum behavior of the
renormalized propagators depends on the lattice bare coupling and interpreted
this fact as the result of it being affected by finite lattice spacing
artifacts. We do not share this interpretation and present here a different and
more suitable explanation for these results.
