ERROR IN MESSAGE: COMPLETE THE ACTIVITY IN MOODLE

Hi,

I´ve created an H5P activity in a Moodle course  (Web: https://www.primariayeso.com)  

In activity settings I´ve marked option: STUDENTS MUST RECEIVE A GRADE TO COMPLETE THIS ACTIVITY.

Why does it still appear the message: COMPLETE THE ACTIVITY in red letters when activity is finished with a 10 score (top score)???

Please could anybody help me? 

Thanks. Regards,

George
