Sorry if this has been reported already but I searched and didn't find anything like this.

I've started a village by curing 2 zombie villagers and grabbing a bell from a nearby abandoned village. Set up houses with sufficient lighting, space, beds and work stations. 
This bug occurs what seems at random times, the villager would have nothing bad happen to them e.g. removing bed, removing workstation, removing bell or hitting them (by accident of course) and their trades would rise beyond their original trade.

If I trade with the villager then it's a coin flip if they will reduce their trade(s) back to their original price or rise their prices more.

I have come from Java edition where hitting a villager means they raise their prices and if you trade with them frequently enough they will reduce their trading prices, it is very much no the same here in Bedrock.

Again sorry if this has been posted already

Thank you
