That's much more deflection than I calculate for those beams? Was there water damage that may be causing the beams to fail. You should address it immediately and be sure there is no water problem.
What is the city and state so I can nail down the snow load?

If you want just one on each side, you will need a 18” deep 2.0E LVL on each side.
