Custom admin bar - new links added not appearing

Hello,

I'm working on a local version of a development site and I'm testing out the Ultimate Branding plugin prior to using it on a live client site.

I've added 2 new links through the "Add new link" part of the "Custom Admin Bar" interface, but neither are appearing in the admin bar.

Is there any reason for this? I appreciate it's going to be difficult to diagnose any problem on a local site, so please let me know which info you need from me in order to make any progress.

Many thanks,
Shaun
