Header/footer is put on first page even when told not to do so in certain circumstance

1) have a core with more than 1 page

2) Go into page settings, and set first page number to 0

3) Go into Style> Header, footer. Turn off "Different odd/even" page numbers, and turn off "Show on first page"

4) type something in the header or footer box

You can see that while the header doesn't show on the ACTUAL first page, it shouldn't show on "page 1" either, because that's what you have it set to emulate as the first page when you do step 2 above.
