See the 1174 in the tick mode column? That is 1174 instances where – in the same bar – TP and SL were both hit … referred to as zero bars.
The Optimiser calculates on TP being hit first, no account being taken of SL during those zero bars 1174 bars.
Your equity curve shows the true result under tick by tick conditions where either TP or SL get hit as price would at each successive tick.
Does that help your understanding?
EDIT /PS
Make TP and SL larger values or optimise for 0 / near zero in the tick column and the backtest results will be closer to the equity curve results.
