Trouble hitting breakpoint due to missing symbol

Hi, I build my engine from source in debug editor configuration.
But there are several spot that the breakpoint won’t ever hit because there are no loaded symbol for that position.

In the picture I can’t hit the line in FProfilerModule class. I think it should be in UE4Editor-Profiler-Win64-Debug.dll or UE4Editor-Profiler.dll, CMIIW.
But those dll isn’t loaded when I try to run the debugger.

Can anyone help? How can I make the debugger loads the required dll n pdb?

Thank you very much for your kind support.
