Can't edit league points

Whenever I try to edit points for a team on the league standings, the app only highlights the line of information about that team but it doesn't allow me to modify any number on that line. 

Edit: Not sure what I was doing wrong but it's working now. 

Edit 2: My app demands me to re enter the License Key. After that worked correctly. Maybe it has to do with it. 

Edited this to inform if is of any use.
