Allocation profiler displays all memory leaks as C++ native memory

I am using AQtimePro version 4.7 for fiunding memory leaks in a c++ module. I used the option Full Check by Classes->by Classes. But still it generates the report about the C++ native memory.  Alll the classes in the module are listed but the count of created , leve etc are 0 for all the classes. IS there something wrong in the configuration here? Please help.
