If a test is included into a course there are various options in the menue "Test configuration":
if "Show results on test homepage" is selected, the new options are still not selectable.
you need to switch to the options menue and select "Adjust configuration " after that the options are selectable.
--> the result view can be adapted in the tab test configuration without changing to "Adapt configuration" in the tab Options
Still the default settings are taken from the options of the learning resource test
