STEP file compound naming problem

[CurssedCoffin]

I'm using core_load_step_with_colors.py to resolve the structure of names of a step file.
I get the names using function GetLabelName() of a label.
But it sometimes returns "COMPOUND" or "SOLID" as the name.
As other software like 3d-tool that compound does actually have a name.
I wonder is there any way to solve this naming problem.
Thank you!
