MB Trading MT4 demo account balance?

Has anyone demoing MBT mt4?
I’m a bit confused how demo account balance is calculated. Basically total balance doesn’t match with all the single trades loss or profit and commisions when they add up together, see pic attached please.


Also in the profit column are the pips profit/loss amounts not actual money, which is fine. But why them pips amounts are added or deducted from the account balance and not a money lost/won on particular trade?

So for example take second row where profit was 2.40.
0.0001 / 1.41648 = 0.0000706 pip value
Trading 1 standard lot then $100,000 x 0.0000706 = $7.06 per pip so
2.40 pips x $7.06 = $16,94 profit on this trade.

Any thougths?

Thanks
