When running a data integrity check on Order Entry we get a few of the following errors on Shipments.

E: Header Mismatch: Number of Lines on Shipment(SHILINES) is incorrect.
E: Header Mismatch: Shipment Item Total Amount(SHIITMTOT) is incorrect.

When I check the shipment the first detail line appears but the rest are missing. The Orders and Invoices are fine.  This issue happened with a few shipments 3 years ago and hasn't occurred since. Can I manually add the detail lines or should I just ignore the error. It's not causing any issues.
