Tuition Transfer Bug?

We have 2 children in university and want to transfer tuition credits from both.  $5000 should go against my wife's return and $5000 against mine.

When I enter this into the dependents section the software does not allocate $5000 to me and $5000 to my wife.  Instead it puts all $10,000 on one return, whichever name I selected last.

 

This does not seem to be correct since the maximum that can be transferred to a parent is $5000.

Is this a bug?
