When playing minecraft with my partner she plays on the Xbox One and i'll jump onto Bedrock Edition on Windows and we'll play together.

We like to get all of the achievements and have done so for many years and often jump back on after an update to get the new achievements and get back to 100% completion.

We had 6 achievements to get so we jumped on and started playing. We noticed that 3 of the achievements were "locked" and we kinda figured that these would unlock upon completion of the other 3 achievements. The 6 achievements were With Our Powers Combined!, It Spreads, Sneak 100, Smithing with style, Careful Restoration and Planting the past (the latter 3 being the ones remaining locked).

Needless to say 3 of the remaining achievements did NOT unlock and so for whatever reason we are unable to 100% the game.

We tried starting a new world, we tried me creating a new world through windows and her joining and we tried it the other way around with her creating the world on Xbox and myself joining but these 3 achievements are always locked regardless of who created or who are in the world.

To clarify the world has not been put into creative. Please see the below video of a world being made from scratch with no behaviour or texture packs or anything attached and the achievements still being unavailible.

Additionally i have noticed that if i do log into the Xbox as myself and open up the game it for some reason it says that i have 41 achievements (out of 83) but i am assuming that this is a result of when i stopped playing console and moved over to PC.
