Error exporting spot colors to PDF X1a.

I ordered a product with spot varnish from the print shop.
During export, Publisher converted the spot color into the CMYK color space in addition to keeping it as a spot color in the shadows.

InDesign exports it correctly.

@wsilmenau It would help if we can get a copy of your Publisher file to confirm the setup as well as you confirming your export settings.
