I was able to use label with the possibility to activate activity completion.
Now new label do not have this option. The time-field is hidden.
If I import an older version of a lable from another course then this label has still this option.
1. As admin set completionfdefault "Do not indicate activity completion"
2. Login as Trainer.
3. Create a course
4. Enable completion tracking in the course
5. Add a label
6. Expected: In Activity completion the drop down box for "Completion tracking" is NOT disabled.
In my moodle it is disabled and I can not change it to "Students can manualy mark the activity as completed"
7. The "Expect completed on" can not be set to be visible.
If the default value completionfedault is set to "Use activity default" then the table can be added in a course and the activity completion can be coonfigured.
