Ah i get it now.
For some reason everything has already your own thumbs up, however this first one does not actually count. I would prefer it to be 0, if there's no thumbs up.
I assume there can only be either no stars, or 5 stars as soon as you get your first thumbs up. Means that there's no meaning to the stars at all, it just shows your thumbs up count between the brackets.
I would suggest to either remove the star rating system, or implement it properly.
And move the rating system to the addon page.
