Yup! We've got that (and a few other tweaks) in a 1.2 ready to upload alongside the first deckplan! Thanks for calling it out. It's really appreciated.
Ah yeah, that's correct. The preceding page is part of the spread marked "TOC" so the header reflects it due to the metadata. I'll remove that header in the next upload.
Hey! I'd have to see what you're seeing, but in my PDF it looks great. The cover should be a stand-alone page so if you have a two page spread with the cover and the black "end paper", it would seem "off".
