Minecraft PS4 Bedrock edition after newest update

I wanted to trade with all of my villagers, so did. I and after that they weren’t able to trade the same Trade again. After trading 12x Times the same trade It didn’t rollback after even a few ingame days or even hours... it just wasn’t available again. So I had to kill them... I think it’s a bug that should be fixed as fast as possible.

Ps. Is it possible to remove the height building limit on Bedrock edition above 128 in hell?
