Iron golem agro issue

In my survival world I tried to make a 2-in-1 Iron farm and villager trading hall. But I dont know why all the golems that spawn get aggro on me while I have done nothing to them nor the villagers. The villagers give me discount and I have good reputation around them but all the iron golem starts attacking me. Even the ones that spawned at the moment. I even let them kill me a couple of times but they dont seem to lose agro. 

The clip shown below is a trimmed version of me waiting for 5 minutes for a golem to spawn and when they spawned they started attacking me
