Admin update WPMU dashboard ?

Hello,

My admins can see WPMU dev dashboard in Plugins, but in Permissions I set that only me can see WPMU, is it normal that they can see it ? WPMU should be hidden from other admins than me, no ?

So now they are asked to update the WPMU dashboard plugin, with Auto-update not possible. More info »

When admin click on "More info" it says : "You have no access to this page" ...
