Premium Themes and theme options page for supporters

Hi, i'm using the supporter plugin for my MU site with premium themes feature.
I put buddypress daily as premium theme but when a supporter activates this theme he doesn't see the options page in the control panel. This problem is true for other themes that should show the options page inside the "Appearence" section which, instead, shows regularly.

Can you please help me with this problem? Might it depend on some setting?
