To reproduce the bug:
- in a course create a quiz
- add several multiple choice question to the quiz
- let students attempt the quiz (best to have hundreds of attempts).
- Once attempts has been made, enter the quiz, select Result tab and select the Item analysis link.
- look at the the first quiz question in the report: at least one question alternative is duplicated. When the duplication occurs on a correct alternative, it also alter the reports.

It would be helpful if you could attach a screenshot please.

In the attached screen shot, the first question shows the duplicated alternative. The question only has five alternatives, while in the analysis there are six alternatives.

This may be related to MDL-12418 since this is a multiple choice question. If there is some sort of formatting going on here, this may be the cause of the duplicate entries in the Item Analysis table for that question.
