Playing Windows10 Bedrock edition V1,16,201 with a friend(2 players!).

I traded with farmers in my village. At first everything was normal. Then they got to the level where I could trade pumpkins. I could trade pumpkins with one villager, but when his trading capacity was up, instead of the pumpkin being crossed out, it just turned red and when selected, you don't get a pumpkin symbol on the right hand side of the screen. the only way to get to sell pumpkins again was to kill all farmers and make new ones. reducing the number of villagers/beds didn't solve the problem. Similar bugs observed with wheat trade. 

Also the village doesn't spawn iron golems any more, nor on normal difficulty monsters inside the village. don't know if those bugs are related.
