Bugs in content types

Hi,

We've been experiencing duplicate characters in the Preview and View modes of Question Sets using the Mark the Words questions.  The duplicate characters aren't in the Edit mode, so there isn't a way to correct them.  It seems to be random.  Here is an example:

The duplicate errors can be found on slides 2, 5, 6, and 9.

Thanks,
Erin

Apart from multiple set questions, the retry button doesn't show. I did check "enable retry" in behavioural settings though. I am in mix mode. Is there something else I should do? Thanks in adavance. 

Hello,

The drag text library does not work properly on mobile phones. As the screen size decreased the missing words move to the end of the page. And then you have to drag them to the upper places of th page. However, this does not work. The words cannot be dragged and the page cannot be moved upwards to reach the correct box in the text. 

thanks,
