Broken Iron farm and the villagers aren't using the fletching tables

I'm not sure if this was caused by the last update but I no longer see iron golems spawning. I got 3 iron ingots after clearing up the leftover iron from the chest meaning it still kinda works but it's all that I was able to collect. I'm also not sure but the villagers might be the main cause of the problem since I don't hear them use the fletching tables. I tried removing the worker blocks and placing them back properly but it didnt seem to work
