This problem occurs:
When using adaptive tasks, where question absence-step has been defined so, that a question can appear more than once in a task.

The amount of answered questions is not displayed correctly in the answer-chart if some questions are answered more than once.
To clarify things, attached following files:

adaptive_results_chart.png
-------------------------------------
Chart shows that the amount of questions to ask has been about 26 (including beginning-cards, instructions etc.).

adaptive_results_export.xls
-------------------------------------
Exported results from the same situation show that the actual amount of answered questions has been 34 (including beginning-cards, instructions etc.). So, based on the difference, the number of questions which have been answered more than once is 8. But that information does not show anywhere in the GUI.

Problems:

• The data what the GUI is displaying is not accurate.
• The person analyzing the results has no idea which of the questions have been asked multiple times, or how many times a certain question has been asked.
• The person analyzing the results can't see from the GUI what has been answered to the multiple asked questions (correct/incorrect).
