granary has bits in it, grains and such like I think. It's a bit heavier iyswim, so you need a bit more white flour to lighten it, otherwise you end up with a very dense loaf. Nothing wrong with that if you like chewing

It's no biggie, we regularly have loaves that rise so much they squash against the window at the top of our breadmaker.
