Report shows duplicated data for all items. I once deleted one of bank account from QB, but it still shows on the report. I don't know how can i remove deleted account.

Hi there, @howardkim206.

The bank account that you deleted or made inactive will not show on your list of accounts. However, when you run a report and include the date that the deleted transactions were made, it will still show. 

For the deleted account not to show in the report, you must customize the date and filter it to make sure that only the account that is not deleted will show.

Here's how:
 

1. Go to Reports.
2. Search the report you want to make and run.
3. Click Customize.
4. Customize the date, then click Filter.
5. Click Run report.

Once done, check the report if the accounts are now correct.
