MR60BHA1 60GHz mmWave Radar -Heartbeat rate output monitors it from 15 to 22 beats per minute, with no waveform plot

I got the SS101990886 module from Pakronics in Australia

the motion detection via the PC serial port it is working perfectly OK, however the Heatbeat rate output monitors it from 15 to 22 beats per minute, with no waveform plot.

Breathing Rate is also non-functional with no waveform plot. I’ve attached a screenshot from the Seeed Studio ( Human-Vital-Sign_Radar.exe) PC software program this particular version uses 72,760 KB.

Could you please advise why I am having this type of output monitoring results.Possibly could be using wrong software version or is it hardware related?

Looking forward to hearing from you.
