Hotpot (plugin)

OK, up to now I had spent quite a lot of time putting together Hot Potatoe quizzes and testing them on my own. This quarter, however, showtime arrived and I have all my quizzes "in production". I'm observing some things that I had not observed in my tests and I'm a bit confused.

Some students complained that the score they see when they click on activities > Hot Potatoes quizzes is very low and they know for sure that they did much better than that. I was rather surprised that something like that would happen because in all my tests the scoring seemed to work well.

When I checked I realized what was going on and I was rather surprised. It turns out that I had selected 'average grade' as the 'grading method' and what was happening was that some students had just viewed the quiz without attempting any answer or had started the quiz but had abandoned it without completing it. So, as the image below shows, the average score they obtained included also what HotPot took to be attempts but which in fact were simply visualizations of the quiz:



My question is, how come the results (or rather 'non-results' as in this case) from 'abandoned' quizzes are computed as well. Shouldn't only the results of quizzes that are completed be included in the calculation of the final score? If completed quizzes cannot be distinguished from abandoned ones, this has consequences also for the other grading methods. Imagine we choose 'first attempt' and then a student first views the quiz one day to see what it's like and next day s/he completes it. Or the opposite, we choose 'last attempt' and the student completes que quiz and next day she checks it again just to consult something in say, a vocabulary exercise, because she just remembered a particular word and wanted to see whether it was the same she saw in the exercise. In the two cases, this student would get a score of zero, which seems rather undesirable.

Is this the way it is supposed to be or am I doing something wrong?
The second question I have is about something that doesn't seem to be so serious of a problem but that is a bit puzzling. I'm getting a lot of labels inside double square brackets (in the image you can see completed, but this happens with many other labels). This didn't happen in the other installation where I did all the testing.

Thanks in advance for any help anybody can offer me with this.
