Backtest using MQL5 cloud returned far many results than it had been requested.

 

Hi there, I have just used MQL5 cloud to perform a backtest with many parameters including 18 moving averages (3-20). The problem is that it returned results for just a few of moving averages. What might have happened?

If I make a backtest using the same parameters and one of the missing moving averages it returns the result normaly. 

Best regards,
