Why would my Crystal Reports template list each line item twice?

Your Crystal Reports template may list each line item twice due to a join in the data source that results in duplicate records. This can occur if there are multiple matching records in a related table, causing the main table's records to be duplicated. Additionally, grouping or summarizing settings might be misconfigured, leading to repeated entries. To resolve this, check the joins in your data source and adjust the grouping settings accordingly.
