Using Custom sidebars isn't working


Your staff recommended yesterday that I install Custom Sidebars to overcome my problem with aquaculture menu showing on every page.

Tried to install it but all I can do is add name and description of custom sidebar on Widgets page and then Define where you want this sidebar to appear. I also chose As UberMenu Widget Area 1 for selected Post Types for where I wanted it to appear and selected Post type Pages.

I can't go any further and UberMenu Widget Area 1 is still there. What am I doing wrong as I don't et anyhtiing like in the tutorial e.g. Pictures of cats onwards.

Please note it woulld be great if I could attach some screen shots, would make explanation much simpler
