CCS/UCC21520: Drive power IGBT using UCC21520

Tool/software: Code Composer Studio

Hi everyone,
I'm trying to do a H-bridge using UCC21520 and power IGBT STGWA19NC60HD VDSmax 600V -> datasheet.

There is my schematic following the datasheet to do a half bridge:


Result:
The low-side voltage Vds work very well. But the high-side give bad output. ( Image below)

Yellow is Vgs.
Blue is Vds of high side.

Unexpected phenomenon:
Vds of High-IGBT oscillate significantly when high-side IGBT is conducting.

I can't find any reason to explain this phenomenon.
Question:
What is the origination of this phenomenon?

Thank you very much.
