help and comments please...

I purchased a new Bosch Universal (mixer only) and have used it twice in the 10 days I have had it. First time made 1 loaf and dough climbed up over the top of the metal dough hook, gluten development was ok, I think it is much better in my KA 600 Pro. Today I made a 4 loaf recipe of 100% whole wheat thinking that with more dough it would help the dough staydown in the bowl better...not to be. This time it even went UNDER the dough hook. Moderate gluten development but was never soft, supple dough despiteadding 1 3/4 cups pf additional flour and hand kneading it.
