Unrealized return & total return not the same, with no sales?

With This Coin, I never had any sales, only purchases.
The Summary on the App (which I cannot find a way to show on the desktop site), shows that the Total return is almost three times of the Unrealized Return. If there were no sales, all return should be unrealized.
The amount on the Unrealized return is correct, the larger amount in the total return is incorrect
