Display default value of template variable

[pmfx]

I have a trivial issue. I cannot display default value of a template variable.

Here is my variable:

Template:

If I save document with value of "Category" template variable set to "General", I have empty value in the output (should be "264"). If I set category to "Other" it is OK and I can see "332" in the output.

Is there a parameter to take default values into account too?
