Hi James,

this is most likely caused by the tolerance which is set directly in the 
problem source code. A parameter on this level takes precedence over 
your course parameter.

You can check this in the meta data "Source Available: ..." in your 
course at the problem. If the source code is available, you can check it 
by using "Browse Resources".

Assuming the tolerance is set in the problem:
If you think this should be changed in general for this specific problem 
so that the problem makes (more) sense, I suggest you directly contact 
the problem author to let him/her update the problem. Go to the problem 
in your course, click "Feedback" and choose "Feedback to resource author".
