Why does the peak cursor not appear in the graph of FFT analysis function in some cases?

When the sound pressure is lower than the measuring lower limit by less than 8dB, the peak is not detected.

 

Ex.) When it is 10-80 dB range and A-weighting, the measuring lower limit is 24 dB. Therefore data of 32 dB or more is detected.
