In the festive mash-up pack world,some material squares are not visible

After open the experimental gameplay in thw festive mash-up world I find that many materials are not visable anymore.The door,the plants,the leaves,even beds.

This has seriously affected my game experience. I really want to play in this mash-up world during Christmas. But now I can't play the game normally, I hope the bug can be solved as soon as possible.

Here I provide 3 screenshots of the game, you can see that the door, sugar cane and leaves on surface are transparent and can be used for perspective
