If you have duplicate transactions that keep reoccurring due to duplicate data provided from the exchange, please do not delete them since our system searches for duplicates based on the TX ID.

Edit one of the duplicates on the "Enter Coins" page and set all the values to zero except the date. 

This way the transaction remains in the system, but is not taken into account for calculations.

In addition you can set up your APIs and CSVs with a new start date so that the dates when duplicates appear are not imported anymore.
