Cosmetic Correction not removing some pixels. Actually makes more hot pixels

[rtemen]

I have a situation where the CC is not eliminating all the hot pixels.
When I use the Real Time Preview window zoomed in on a particular area, when sliding the Sigma level to the left (smaller) this pixel will not go away.
In fact, when the Sigma slider goes all the way down to 0, it turns that one pixel into three pixels.

Any help is appreciated.

It turns out that if I turned off the Hot Pixel Threshold and used the Auto Detect with the Hot Sigma left a 3.0, they all disappeared.

Did anyone ever figure out why this happened?  I'm having the very same issue.  I had not done any image processing since the fall of 2018.  I recently installed the latest Pixinsight version and changing the hot pixel sigma slider does not seem to make any difference like it used to.
