I have a course with groups. The couse has a quiz on which the students must submit a document with the answers.
When I select the gradebook, I only see the selection of the first group, but the groupselector is not visible.
In the css it appears that the class groupselector gets the property display: none.
To my opinion this property should not be set. I really cannot find in the documentation (and in the coding) where this property is changed, beause in my theme it is set to display: inline-block
Please help.
