Question about staking and realized/unrealized gains

I just started to track my investments with a spreadsheet that calculates the total deposit I did on my exchange account, the current value of all my portfolio and reazlied/unrealized gains.

If I don't track any staking rewards my (unrealized gains + realized gains) is equal to (portfolio value - total deposit from bank), which means it is correct, right?

However since I started to track my staking (which I calculate the daily cost basis and average them with my current holdings, thus this mean that realized/unrealized gains are influenced by staking), I realized that my (unrealized gains + realized gains) is not equal to (portfolio value - total deposit from bank).

Can somebody please explain me if this is correct? Am I doing something wrong?
