Problems inserting favorites button

hi,
If i insert the favorites button via plugin settings, using the post filter options, it will add a text ‘favorites 1″ to excerpt posts in category archive pages.

If i choose before post, my post will start with “favorites 0 Lorem ipsum dolor sit amet etc..”

If i choose end of post, my post will start with “post content” and at the end i will have “favorites 0”

If i insert the favorites button diretly in the template, i can’t save favorites.

I prefer the first solution, but how to remove the “favorites 01” text that is added to excerpt?

If someone encounter the same problem and find a fix, could you please share the solution?

Thanks
