Unknown Data Values

I just purchased and tried out the MR60BHA1 sensor. I used the program given at 60GHz mmWave Static Breathing and Heartbeat | Seeed Studio Wiki

When running the program the output value of the program can be seen. But what I’m confused about is that there are some values ​​that I don’t know what they are. How do I do it if I want to remove it?
