How are realised returns calculated, why does my portfolio have negative realised returns even though I never redeemed my holdings?

`The "Realized Returns" value represents the total amount withdrawn from your investment to your Mudrex USDT wallet. This includes both the realized profit and any portion of the original investment that has been withdrawn.

Since the wallet cannot differentiate between the profit and the initial investment being withdrawn, it simply reflects the total amount withdrawn as part of the invested value. In short, the "Realized Returns" figure shows the combined amount of profit and investment moved back to your main wallet.
