We are unable to get the full report after we bought a monthly subscription of Kobo (https://kf.kobotoolbox.org). The main issue is when we try to check the report of a particular user using filter function, their old details are missing, their names are not showing.

Welcome to the community, @wash_o! Could you kindly share a screenshot so we can understand your issue pictorially and help you out?
