in LR5 it was easy to apply a user defined preset to a set of selected photos by right click to the set going to "Entwicklungseinstellungen" (development settings) and then poped up a list of choices including the whole set of presets. By choosing one of them the preset was adapted by all photos of the selestion. In LR6 I can start the same way but in the popped up list of choices the presets are not more listed. How I can solve this problem?
Select all images to develop (working in the library grid view),
In the Quick Develop panel, click the drop-down menu for "Saved Preset"
Choose your required preset.
