Ouster LiDAR with Color Annotation PLY Format labels range from 0 to 34

[sputnik4]

Good day Rellis-3D,

I tried to check the labels of each point, and it seems that some points have a label greater than 20. For example, many points have labels from 21 to 34.
Do I have to ignore these labels that are greater than 20?

I was able to access the classes and here they are:

void = 0, grass = 3, tree = 4, pole = 5 water = 6, vehicle = 8, log = 15, person = 17, fence = 18, bush = 19, concrete = 23, barrier = 27, puddle = 31, mud = 33, rubble = 34
