[Koha] patrons receiving overdue notice for checked in items

Hello We are having instances where patrons are receiving overdue notices for items they have already checked in - for example I received one today for an item which was checked in on Friday and is not now on my patron account. Any ideas? Regards Lisa [Description: Description: Description: CR_logo_POS_COULEUR b] LISA PEEL, PGDip, MA.
