Problem FORM CUSTOMIZATION modx 2.3.1-pl

hello!, i've a problem with form customization when I create a new set using constraint "parent".
For example, the label "Constraint Field" has the value "parent" and the label "Constraint" has the value "4". Then, I uncheked the label isFolder and I uncheked one template variable. In the childs of document 4 everything works nicely, but in the other resources (documents) something strange happens. The label isFolder appears ( as we haven't set any FC ) but the template variable dissapear. It seems that the constraint affect all documents for TVs, and not only the childs of document 4.

Is this a bug or I'm doing something wrong?

I'm getting the same thing in ver. 2.2.2 so i dont think its us being weird haha.

Tried other customizations such which don't include constraints and they work fine, but as soon as i add a constraint such as parent, id, menutitle, pagetitle and value it affects all resources.

Cheers,

Alex
