Steps to reproduce:

1. Ensure you own the Halloween Mash-up pack
2. Create a new world with the Halloween Mash-up world template
3. Go to -85 64 73
4. Go to -15 64 34
5. Go to other locations visible in the screenshots

Observed result:
At the first location, there is a missing half slab and the item frame does not have a carved pumpkin inside of it. At the second location, a piece of pink wool is placed. Other places also have wrong/missing block placements.

Expected result:
At the first location, the half slab is present and the item frame is attached to the half slab and has a carved pumpkin inside of it. At the second location, a piece of green wool is placed instead of pink wool. The other block placements are consistent with Legacy Console Edition.

Original description:
I put an image where it is shown that in minecraft bedrock are misplaced a wooden block (I'll point out your mistake in the image), while the image of minecraft console edition has its wooden block as it should normally be seen.
Also a pumpkin is missing on the top of a tent in the bedrock version while the console edition has it (I share images).
I have added more screenshots, about the same problem and in the images I put with blue check mark the ones that are right (those are from the console edition version) while the ones with red circle are the wrong (or missing) objects that I point out (those are from the Bedrock version).
