Abstract Recently COMPASS has reported unexpected results concerning K$^{-}$ over K$^+$ multiplicity ratio for kaons produced in DIS with a large fraction of the virtual-photon energy, PLB 786 (2018) 390. The obtained ratio is significantly below the lower limit given by NLO pQCD.In order to provide more information about the observed phenomenon we show for the first time results concerning $\bar{\rm p}$ over p multiplicity ratio for protons produced in DIS with a large fraction of the virtual-photon energy. In addition the kaon multiplicity ratio is presented in an extended kinematic phase-space with respect to the one used in the aforementioned paper.
