Backtesting issues!!

[dnighttrader]

I was backtesting a simple crossover strategy and I came across the following error, which maybe someone experienced before, if I run the backtest from January up to the end of March, the result is negative but if I run it month to month always finish positive how you can explain that. Do I miss something or do I have data issues? I attached the pictures so you can see the results.
