[2022] Premium Subs In Naval Battles?

Combination of a mistake and the-bestest-luck-in-the-world <3

The Soviet and IJN Subs were not supposed to have a category, so that is the mistake. The-best-luck-in-the-world is that the nation/type is chosen by automation, so perhaps there's a bias on newly-added categories being chosen? I've asked if there's a way to intentionally set a section to be x2 but it's not a process we use so the assumption is no.

We're unable to disable the Soviet and IJN Sub category since they are already active, but we'll be removing them so they won't exist for future Naval Battles. That'll fix the problem going forward.
