I already know where is the problem. When I change field "Material type" in "Manage materials ..." from PETG to PLA, the "Recommended" button starts working and I can choose from the line height options. I can't judge if this is an error or a feature.

When I resize the nozzle, all profiles in the right panel in the drop down list are lost. Also, I can't change the layer height that is typical for a given nozzle via the recommended button. It only helps to add a new printer, and then previously saved profiles will appear in the right panel. Sorry for my english.
