Did you use Ctrl-F9 to create the two new pairs of field braces for the '(FP-{={PAGE}+1} Blank)' part? (note: I corrected a typo in the field code after my original post.)

As for your work document, you need to check that the Schematics portion does, in fact start on an odd page and that it's not using all those Section breaks you referred to earlier.

FWIW, it also occurs to me that the page numbering fields for your Schematics portion could be greatly simplified by the use of a 'different odd and even' page layout for that portion. With such a setup, you could insert just the following field code & text in the odd-page header:
FP-{PAGE} (FP-{={PAGE}+1} Blank)
