Common problem with a bike set up with a low bar. Even more common with lots of set back. Ive never had this problem and ride with 100mm of drop to the tops. I can ride full power in the drops with bent arms and not hit my chest but then I am 6'2" and 160# very flexible and people are ALWAYS saying I look skinny. If you are heavier than that then you might have to put up with it.

you say you are comfortable so I wouldnt change anything. Just enjoy the aero benefit of a lower bar.
