Form-based T/F quiz doesn't work when we allow more than 1 attempt

Hi, 

I'm relatively new to SL2. We want to allow more than 1 attempt for a T/F question. But the T/F form-based quiz doesn't seem to work for >1 attempt. When I set it to allow for 2 attempts, and proceed to select and submit the incorrect answer, it automatically takes me to the next slide. I would like to allow the user to try again instead of taking them to the next slide. But is this behaviour supposed to occur (i.e. because if one answer is incorrect, there is only 1 other answer), or is there some setting I'm missing to make that happen?

Thanks!
