PI Backtest Signals missing!

Hello Community,

I backtested BANKNIFTYMAY15 15-minute 500 bars.

On back-test of below script in latest PI 1.0.0.6, I am surprised to find there are many missing Signals !! They are shown in White comments on chart.

In below Trades List also you see LONGS are Not followed by EXIT LONGS, and SHORTS are not followed by EXIT SHORTS, even when PSAR Crossover signals are present !!.

Buy script

CROSSOVER(EMA(close,5),EMA(close,10))

Exit Long Script

CROSSOVER(PSAR(last,0.03,0.3),last)

Sell Script

CROSSOVER(EMA(close,10),EMA(close,5))

Exit Short Script

CROSSOVER(last,PSAR(last,0.03,0.3))
