Decimation Master USE and KEEP polypaint is not working properly

I am currently using the 2021.6.6. When I am decimating using USE AND KEEP POLYPAINT, the mesh goes mostly black. It contains color information in some places. I didn’t use this feature in the previous versions. But, it was okay a few days ago. What am I doing wrong that the polypaint color is changing after decimation?
