FFT Window Issue and differences

I am working on FFT measurements using DSA -X 91604A series oscilloscope and was analyzing the different FFT windows -Flat,Han,Ham,Rect & Blackman Harris which the scope provides.

While comparing i see that with the same setup the measured Magnitude of a spectral peak for a *blackman harris window is
8-10dBm less compared to the other windows available.*

Is it a bug? Can you please provide some insight?
