That is because AFAIK you can't use two trees on one page. They use the 
same variable names, and will conflict with each other. You could try and 
combine the two trees by doing something like this:

<!--#tree answers_and_questions sort=objecttype-->
  <SPAN CLASS="tree">
     <!--#var title-->
  </SPAN>
<!--#/tree-->

where answers_and_questions is a Folder object containing the answers and 
the questions objects, and each answer and question have a property called 
'objecttype', one with value 'answer', and one with the value 'question'. 
Set these values on the answers and questions objects as well.
