Sync v2 is still being polished, hence it’s not the default just yet.
It syncs records, not history. Most of the time records are history, but not always. The remote history table for you is empty, because it’s all in the record store instead.
We should probably just hide that from the status if the new sync is enabled. We could replace it with the remote record count, but I’d rather avoid a bunch of remote counts atm
