I wondered about that too, but figured it out:
if you scroll down to the bottom of the forum threads page & look under "Display Options", it defaults to showing only threads active in the last two months. as the sub-forum isn't that active I was only seeing a couple of threads. you can change that to a longer timescale to see more threads.
