KrafterPRO Question

While I was still overwhelmed by the amount of color shades, tints etc that have been created, I cleaned out those colors that I will never use. When I do that I come down to maybe 10-15 in D5.
However, when I re-run the KrafterPro Audit Scan, the old number (96) doesn't change. Bug? Some cache I don't know about? Wrong way to approach this? Using v4.1.26

Thanks
