In the Transactions tab you can edit a single transaction or check multiple boxes on the left and apply to the same edit to all the checked transactions.
If you find a duplicate transaction, click on the drop down menu to the right and “Mark as Ignore”.
If you find a transaction you that you think is a non-taxable transfer between your own accounts and ZenLedger marked it as a sale- you can "Mark as Ignore".
You can then re-run your reports and our system will update your reports. 

To re-run your reports:
You start the report re-run by clicking on Dashboard.
Then Import More Transactions.
Then Finish Importing Transactions on the bottom right. Then just go through the import flow (mark airdrops and forks, select FIFO/LIFO) and let the system generate your updated reports.
