Villages still spawn when "village" isn't in the preset

I tried making a house on a superflat world in Creative.

Seed used: "-6381345746738792321"
Preset used: "2;5x7,52x1,5x3,2;1"

I teleported to 0 in the X-axis, 63 in the Y-axis, and 0 in the Z-axis. I found a village near the coordinates, but I didn't even type "village" in the preset. Same thing with all of the game rules. I think this might be a bug or something?
