In RedTrack, there is no option to remove the data. So if you have uploaded the same conversion several times, as a workaround, you can update the payout for conversions in the statistics.
How to update the conversion payout
Step 1. Open Offer source settings in RedTrack and choose the Mode - "Keep original data, Increment payout". Wait a few minutes.
Step 2. Go to Logs -> Conversions -> click on "Add conversions":
Step 3. Add Click ID of duplicate conversions and payout difference with a negative sign, save the changes.
How it looks like
For example, you have three conversions with the same Click ID (5dc07adbbdbbb400012e8195) and payout $20 (total $60). In this case, the payout difference is $40.
Apply the "Add conversions" option, add Click ID and payout amount -40 as it is shown in the screenshot and click on Save.
Though the number of conversions remains the same in the conversion report, the payout will be shown correctly.
