Okay.. very odd. Suddenly, two books I've been reading show up as "On Device". I've added a bunch more, but they don't show up after a restart of calibre / reconnect of the device.
I tried opening a third book in Koreader, but that's not it either.
I found this "The solution to sending eBooks to the Kobo is to go back to Nickel when you want to add more eBook(s)."
What does that mean? What is Nickel? Nickel Menu?
I tried exiting Koreader and starting Koreader again from Nickelmenu, but that wasn't it.
Tried restarting the device as well.

Okay.. the two books that do show up in Calibre, show up outside of Koreader, in the default Kobo interface.
The rest of the books do not.
Found this, has instructions for a plugin to update the data, but that doesn't seem to do anything either:
