I'd be pleased to help you fix your discrepancy report. It's possible that these items were deleted and was recreated the reason why it's visible on your register. However, once the transactions are reconciled and accidentally removed, these items will show as deleted on the report.
To better isolate the issue, let's go to the Audit Log to verify if there are transactions that were deleted. Here's how:
Go to the Gear icon at the upper right.
Select Audit Log under Tools.
Click the Filter drop-down.
Select the appropriate User, Date, or Events to narrow the results.
