No "Custom Admin Bar" section showing up in "Settings"

My Site is a multisite install, but I only want this plugin for one of the sites.

When I activate the plugin for the individual site, it does not display a settings link in the "settings" menu.

I then tried "Network Activate" and it worked fine at the network level, but still not at the individual site level.

Any ideas?

I have used this plugin without issue on non-multisite installs.

Thanks
Chris
