So we have a quiet hammer, a sly clerk, a gormless ox, and a fighter crab.
So, good money is on all the maps being correct. There was a village here named X, there was also a village here named Y, and now there is no village here.
Most mundane answer is that it gets destroyed every so often and rebuilt but that feels like something Zhuan Kun may have known about, even if i kinda think thats giving him too much credit here. The real indication given by his lack of knowledge is that whatever is going on here is subtle, has likely been going on for a long time, and probably not enough to simply snare the vassal mapmakers.
In any case, merchants sell to people and this place is so off the beaten path it feels unlikely that this one would be using it as a shortcut so that lends some support to the idea of there being a village around.
Finding the merchants map seems to be a good first step here for cross referencing purposes. Or perhaps second. Seems to be deliberately parked and his ox set to graze so he might be around if hes alive. Find the merchant first.
