When I import my crypto/fiat/card files to Koinly, my fiat balance is wrong.
Workaround
I need to manually fix duplicated/unecessary fiat-only transactions for my balance to be correct.
Note:
Incorrect fiat balances
do not
affect capital gains calculations on crypto transactions and aren't even included in any of Koinly's reports. As such, this is more of a visual issue.
