I use StampManage USA and can sympathize with your distress. Unfortunately, the database contains inconsistencies, many errors, data in the wrong fields, etc. which I attempt to correct. At the next update, I have to make the corrections over again. I believe the issue occurs because there are many contributors to the database, and apparently no one filters their inputs. I would like to ask the administrator if it is possible that when program updates are provided, they only add new data (new stamp issues) and do not change existing data. Updating poor stamp images and current stamp values would also be welcomed.
