Why does my Iron Phoenix no longer spawn Golems?

So all I have done is moved the 40 something villagers away from the farm one block. I did that a while ago and it still didn’t work because I had fiddled with other things. I put everything back to how tango says to make it, except the villagers. They are 1 block further away from the machine. I afked over night and got a double chest and a half of iron, so I would say it works now.

I accidentally left the area. So I manually put all the villagers back to their starting positions, unloaded the chunks for a few minutes, came back and started it up. It seems to be working still.
