By best guess is that Hulk has a lot of free time. It's still possible for him being part of two teams at the same time. Let's say that one mission with either team takes him one day. There are still other 6 days in the week.

The Modular Armor and the Hulkbuster probably had the same numeration because the Hulkbuster is supposed to be a Modular Armor add-on. I guess the All-New Iron Manual considered them to be different armors (the Hulkbuster is more than just a regular add-on).
