Permalink menu missing with plugin installed

Please can you help? I recently had to re-save permalinks on the sites of my multisite network as another plugin was causing issues.
However the permalink menu item is missing from each of the sites settings menu with Ultimate branding plug installed. It took some time to isolate the plugin ; I can now resolve the problem by temporarily deleting the Ultimate branding plugin folder. However I would prefer not to have the conflict with wordpress, am I missing something or is this a fault?

This is linked to another support request regarding the subscribe by email plugin.

Many Thanks, Steve
