The third screenshot is a structure block issue. It didn’t clear those blocks when it generated. It just has to do with that specific farm tile.
All I can say for this is that it has to make sure you bought it when it loads. Make sure you have connection when trying to load it.
When you do anything that turns off achievements you can’t turn them back on. Even if you don’t load the world, if you set it to creative or turn on cheats before entering the world it still counts.
But this is in Bedrock Edition, and when I posted this, was the only one mentioning anything close to my current problem. I don’t understand how this is not the correct place to post this.
