In PS 2019 when you create a depth map and go to Filter>lens blur, and activate the Depth Map, you can no longer click on the image to change the depth of field accurately. Clicking does not pick up the accurate value form 0-255. You have to move the slider to get all the values
Do you already know that in the Develop module if you draw a gradient and then type H to hide the pin, if you type H again it deletes the pin. In fact every second tap of H deletes the pin whether it starts visible or hidden. I just tried Radial and Brush and the same problem.
