MobiUnpack (stand-alone or plugin) will split a hybrid mobi/kf8 into its individual components. There's no guarantee that the resulting file would be 100% identical
to what would be produced by the KDP process (although I suspect it's as close as reverse-engineering efforts can get), but if the issue "goes away" on the KF8-only file, it could narrow down where to look.

This seems to resolve when the book is uploaded to KDP.
I was never quite sure if KG was adding two text Guide items, or if that was a glitch produced by whatever tool I used to unpack the MOBI. There's a bit of a catch-22 there, though. One has to unpack
the mobi in order to see if there's an extra text Guide item (let alone be able to remove
that extra guide item from the OPF) ... but if KG is
responsible for adding two text guide items, it's going to put both right back when one rebuilds the MOBI.
I do suspect
KG is responsible, though. If only because I have a pretty firm grip on the mobi_unpack code (and also because I don't believe a calibre-built KF8 [hybrid or stand-alone] exhibits the same behavior).
