Whoa! You are jumping too fast here and making wrong assumptions.

The trap nulls are pretty obvious and should be more dramatic. You should aim to getting about two to four volts across the detector load on the VTVM. The trap is nulling out. If so you increase the signal level until you see a good null. Did you do all the traps properly? It is very important before you move on.
