Short update. We tried to figure out what the software problem is. We believe, it is a refresh problem. When you apply the preset, you do not see something happening, but in fact, it is there. When you go into the radial filter tool, you see the pin. When you click on the pin and move it around, the preset settings are applied and you can see them on the screen. Same bug in Camera RAW and Lightroom mobile (smarthpone/iPad).
