matches after group stage dont add

Hi,

i am doing Copa America pool for the office, i imported the csv with all matches but after group stage matches didn´t add. If i download game schedule, they are all the matches in the csv, but they dont appear nor matches page not even in the matches section of the plugin. In player predictions page appears this way: http://i.gyazo.com/d3beb7be2722dcc54d6a058c83269fd3.png

What could it be?
