Save for, maybe the DeathStalker and the Nevermores, none of the ones that broke in were "ancient". My issue is less that the grimm that were there weren't a threat. My issue is that more threatening grimm didn't show up. Massive cave systems near the site of one of mankind's greatest disasters is hardly a place I'd expect hunters/huntresses to patrol and thin out the population. I mean, any grimm that were there when Mountain Glenn fell, would have a good chance of still being alive.

Not to mention, it seemed implied that the cave systems were discovered when the people of Mountain Glenn sheltered in the tunnels. So it is very unlikely that anyone had ventured into them to hunt Grimm before. I'd expect those caves to be absolutely filled with the most ancient grimm possible.
