not all indicators appear in strategy tester

 

I came across an unusual situation: 

I put all the indicators I need in a class in a separate header file. When I run the strategy tester I am able to see 4 of them instead of 6! 

even though the EA is able to read their values at any candle ( ie handle is valid, copybuffer is valid , Indicator(0,1) = double). 

to make sure that the indicator header file and class is bug free I included it in another simple EA and it worked as it is supposed to.

My question is, how to troubleshoot this bug? 

how to get the strategy tester show all the indicators in the header file ?

which part of the code might be useful so I will post it?
