custom sidebars pro makes no sense to me

This plugin makes no sense to me --

I use conditional widgets -- which from what I read is the same thing ---

This plugin does not add new sidebars ---

so I created a new sidebar called left of logo --

I placed a sidebar on my screen and used left of logo --

There is no where to drag a widget ??????

so I go to my page and on the right it has all the theme sidebars
so I take the drop downs for left submenu sidebar and choose my new sidebar left of logo

Now I go to widgets and try to drag and drop something into the left submenu -- will not take it
try to drag something into left of logo -- will not take it --

Why didn't I just use left submenu for my area to start with??

Why the extra layer???
