Groups teampage legends settings

if you go into the acp/users and groups/manage groups/settings and remove both the default admin and moderator groups for the legend and teampage then go and try to add a group to the legend click submit then go back and click to show it in the teampage and click submit then go back and the legend box will become unchecked or vise versa but instead if you check the legend box and the teampage box together theres no problem of course you'll have to clear out all groups from the legend and teampage first though
