[Koha] restriction period for several overdues

Hello again, We're working on Koha 3.16.03, and we've noticed that when checking in some items with overdues Koha only takes the first checked in item to apply the restriction period to that borrower. We check in an overdue item, and then automatically Koha sets a restriction period to the patron. If you immediately do the same process with another overdue item for the same patron, it doesn't update the patron restriction period, which remains with the same number of days than before. Has anyone checked this behavior? Is this a bug we should report to the Koha community? We'd thank any comment on this issue. Regards, Carolina Andreu Dpto.
