I also experienced this issue – not on a multi-site, though.
It came down to permissions, for me. If I install the plugin manually, the permissions are set to 644 for files and 755 for directories. If I change the permissions for files to 755, I can then see all available options for the plugin.
I’m not sure what is causing this, though. I use wordpress in a way that allows me to lock down files so I can version control everything. Is this plugin attempting to make changes to its own files?
