Adobe LiveCycle - checked check box not hiding subforms

I am creating a PDF form in Adobe LiveCylce that has sections that can be check boxed "None" and the section (subform(s)) will "disappear" (become hidden). This is done in the Action Builder with the condition when check box is checked, set the visibility of the subform to hidden. There is also an opposite action, when the "None" check box is unchecked, the hidden section will become visible. This works with most of the check boxes/subforms on the form, but some will not work (stay visible no matter what).

Any ideas?
