Super Mario Mash-Up Pack doesn’t work well

Version 1.21.71

Hello, good morning. I’m reaching out to report an issue related to the Minecraft game on Nintendo Switch.

When activating the “Super Mario Mash-Up Pack,” the main menu backgrounds used to display special colors (orange, light blue, and magenta). However, since October 2024, they have reverted to the standard Minecraft backgrounds (red, magenta, and white), even though the pack is still active.

Additionally, I’ve noticed that the water in the swamps, which used to be purple, now appears brown—just like in the standard version of the game.

I would appreciate your help in finding out if there is any update or solution available to fix this issue.

I look forward to your response. Thank you very much!
