Yeah I see, unfortunately I can’t test it now with the Topic Ratings Plugin but I think I know what is happening here. 
The Topic Ratings Plugin use this code for the link-top-line element.
It is shrinking the link-top-line in FKB Pro theme and this is why the category badge placed above the user datas because that is the width of the element byline which contains the category badge and user datas so this is depends on how width is this element.
