Results from attempts in a pick many question are wrong
I have a pick many question where the user has to select the 10 hazards in the image.
I have given them 3 attempts, and instead of using states I am using layers (as I only want the area in the image to be clickable once).
I am doing some testing on it and if I select all 10 hazards in the first attempt I get "correct" feedback.
However if I select the incorrect hazards for the first or second attempt, but then select the correct ones for the second or third attempt, I get told that I have not selected the correct ones, even though I have.
I am very confused as to why this is happening. I have checked my pick many results and the correct ones are selected, so not sure where the fault lies. I have attached the .story file is someone could have a look and point out where I'm going wrong, I would really appreciate it.
