Hm. Are you also aware that the state of those buttons is set and maintained *individually* for each Layout (e.g. when you click the Terrain button up top, the settings will be different by default from if you clicked Atmosphere, *and* if you change them in either place, it will remember those changes *per-layout*). Additionally, these settings are not maintained across sessions, so it will reset if you close and open TG later, or if you open or create a new file.
