Considering the reaction schemes (20) and (21) in Fornari et al., 2020, the fragmentation terms F_i (Eq. (22) in Fornari et al., 2020) are not correct. Thus, the fragmentation terms F_i (Eq. (12) in Fornari et al., 2020) are also incorrect when the reaction schemes (10) and (11) in Fornari et al., 2020 are taken into account. Here, the correct equations will be presented.
