If you choose not to arrange a region's contained objects then there is no way to switch back using the GUI. Once you've done that the arrangement panel no longer appears in the inspector for that region. You have to use the console to switch back.
display.setArrangedAxis(network.findRegion('R1'), axis='largest')
