You don't say anything about how high it rose each time. I would
suspect a yeast problem. Are you sure you yeast is fresh? Did you
carefully note the size of the dough when you set it to rise and after
it had risen? Your recipe doesn't say anything about how high the
dough should be expected to rise (usually it should double or nearly
double). "Let rise for 1hr" is far too vague; the recipe should specify
a size. Also small temperature variations (in the room or the water
added) can make a huge difference in the action of the yeast. The
recipe calls for "warm" water. That's too vague -temperature can be
critical. You should get a new book (unless you have lots of time on
your hands -and money for wasted food). I'd recommend "The Bread
Bible" or "The Bread Baker's Apprentice". Also Kneading for 10mins in
a Stand mixer -especially when the dough batch is so large- may be too
long. You should stop when the dough passes the "Window test" and is
about 77-81degrees - a fixed time may not be good all the time. Also
I'd advise you to get a digital scale and use a recipe that gives
measurements by weight not by volume (as both books mentioned do).
Let us know when you get it figured out.
