not showing votes at homepage and widget

i have 2 problems with the plugin:

1. directly in posts i can see votes (and can do votes), but at the homepage or category views there are always 0 votes… at every post.

2. the widget always shows: There were no results fitting your criteria. but there are a lot of votes. of corse i have activate the widget for showing posts votes.

so whats wrong?
