The reason is that:

1) unchecked checkboxes do not make it into php
2) because you're not specifying an index for the array (level[]), php will 
create it for you automatically

So instead of using just 


specify the level explicitly:

  name="level[0]", name="level[1]", etc

NB you should do the same for prob[] as well.

Having done that then in your example you should get something like:

 $prob[0]: Problem one
 $prob[1]: Problem two          $level[1]:      High
 $prob[2]: Problem three        $level[2]:      Low

NB that $level[0] is undefined.
