Google analytics for WPMU and supporter...

I have trouble making the google analytics plugin a supporter only feature.

In Google Analytics plugin settings (network admin-->settings-->Google Analytics) there is a setting for this, but it does not seem to work. If set the option "Google Analytics Supporter " == enabled Google Analytics is still visible on non-supporter blog. Also If I reload the Google Analytics settings page it always shows "Google Analytics Supporter" as disabled.

Do I need to make some other settings as well ?

I have latest versions of both plugins (GA plugin version 1.1.9) and WP 3.1. Otherwise these plugins are working correctly.

Thanks for your help...

#Edit:

I have also supporter premium-plugins enabled. Do I need to set Google analytics as a supporter only plugin there as well ?
