When I cite a paper in the main text with more than 2 authors I want biblatex to add et al. This is happening but at the end of the document in References only one author is shown with et al.
\usepackage[backend=biber,style=authoryear,dashed=false,natbib=true,url=true,bibencoding=utf8]{biblatex}
This is what I get
Any ideas please?
