Game Naturally Spawning Multiple Wandering Traders

My game has spawned multiple Wandering Traders simultaneously, which according to snapshot 19w05a ought to be impossible (it's stated that only one exists per world). One spawned near a village I had been building on my Survival world (comprised of only two villagers at the time) and another spawned near my house (roughly 80-100 blocks from the village site) one in-game day later. I've included a screenshot of the two traders together at the built village, as well as what I believe to be the logs from the play session (the logs may be rather long, but I exited the session shortly after this happened so any relevant data ought to be close to the end of the logs).
