How to reset Minecraft village?

I’m playing Minecraft 1.14 on my server and I have a village with 2 Lev, 3 farmers, 2 composters, 4 beds, 1 bell, everything is in a 4 times 19 rectangle surrounded by fence. For some reason the farmers won’t enter love mode, so my idea was to try to reset village.

Todo list to reset Minecraft village:

  • To remove all village data other than the farmers’ profession and trades, is it enough to remove the beds and wait, or do I need to remove the bell and/or job stations too?
  • How long do I have to wait to see if the game no longer thinks there is a village there, and is there a way to check w/out mods to make sure the village is gone?
  • I also have my bed about 15 blocks away on the other side of the fence, and my crafting stations. Do I need to remove those too?
  • Lastly, I have some beds and crafting stations about 20 blocks underground, as part of a planned iron farm, but no villagers yet. Do those have to go?
