Tasktype Utilize

Just yesterday I used a tasktype utilize in my tasksequence (Flexsim 5.1). I usually just fill the task with all variables although they are not used in each tasktype. For the utilize task var2-var4 should be N/A. If you've put a non-zero value as a var2 value, the system console pops up with an error. Would be nice if it still works although you've filled in non used values.
