AlgoWizard - Closing orders does not always Close the Full Position Size in Large Strategies

In AlgoWizard (Build 130.467), when running backtests in MT4, some orders do not get closed properly. They are only partially closed and then later the remaining lot size is mysteriously opened as another order. 


The attached strategy illustrates the issue. In the screenshot 'RandomPriceTrader v1 Backtest - Results.PNG', note Line 4 - Buy #3 for 1.10 lot, then on Line 6 - Close #3 for 1.00 lot (which should be 1.10 lot), and then Line 7 - Buy #5 for 0.10 lot. This Buy #5 is not initiated by the strategy and does not even show up in the Journal. It sounds like something going on within MT4 but I can't explain it. Since their are several weird behaviors with this strategy in AlgoWizard, I suspect it may be the cause of this issue.
