Z-wave device channel linking

Hi I have aeon z-wave controller as well as some z-wave sensors , I have configured sensors, when i have deleted sensor using paper ui it is getting deleted. After that when I Added the z-wave devices using paper ui , those are get added, but the channels are not getting linked automatically (I have go to things -> channels to link each and every channel), But the same is working for sony tv and sonos player,as well as for hue

What is problem , I am not understanding???

Do you have the “Simple Mode” checked at Configuration->System->Item Linking?
