I'm a new user for Logic Pro X, during my installation of LPX, I noticed after I downloaded "Essential sounds",it shows a "sound library manager"window which includes all the sound resources which I've not downloaded, I clicked the "Select all uninstalled" button on the window, and scroll down to check if all have been selected,but I saw the last part"legacy & compatibility" won't be selected automatically after I clicked that button and its status shows "Incomplete", I'm not sure if it's a default download settings for the new users, do I need to manually select this part for download?
