Plugins menus in dashboard

I have 4 installations running WP 3.5 and BP 1.6.2. There are some plugins for which on one site I see the plugin specific menu in the Site Admin dashboard, and on other sites I see it in the Network Admin dashboard. Examples include Automessage, BP Groupomatic, Activity, and Mobile Detector. I cannot figure out the rhyme or reason why I see one behavior on one installation, and something different in another installation.
