Hello team.

Failure in a particular scenario.

When a "Description" question is created within a Heading Section in quiz questions and want to make use of the new functionality "Set up a grade for each section" it generates an incorrect association in the "Description" questions.

Steps to replicate:

• Create a new Course
• In that new Course, create a Quiz
• In the created Quiz, add sections and questions.
• You can create more than one section (minimum 1).
• Each section must have at least 2 questions and one of those questions must be of type "Description" ( ) .
• Click on "Grade items setup" in the top selector.
• In the "Grade items setup" view you can see that each section shows all questions except the "Description" questions ( ).
• Click on "Set up a grade for each section".
• You can see the "Grade items setup" table where each associated Heading Section cannot be deleted ( ).
• When you press the "Reset Setup" button you can see the error ( ).

Remarks:
The reason for this error is that at the time of calling function:
`public function update_slot_grade_item`.
in the file:
`mod/quiz/quiz/classes/structure.php`

It is being stored in the table 'prefix_quiz_slots' in the field `quizgradeitemid` of all the questions that compose this Section, even those of type "Description" that are not visible in the interface.
