EA in tester does not trade most of YEN pairs


I tested my EA in tester and suddenly discovered mysterious problem. EA does not trade YEN pairs except USDJPY.  But has no problem with live trading, all yen pairs works there.

Digits as always:

 int digits_adjust=1;
   if(m_symbol.Digits()==3 || m_symbol.Digits()==5)

I thought maybe it comes from suffix but USDJPY+ also works in tester.
