Mash-Up Packs Maps visual glitch

In Mash-Up packs like Adventure Time, the game maps do not adapt to the Mash-Up packs and the colors of the blocks drawn on the map are from the base minecraft and not from the Mash-Up pack that is being used at the time. For example, in the Adventure Time Mash-Up pack in the console version the map used to be very colourfull, after the bedrock update in PS4 it just looks like in the base minecraft. Please fix this visual glitch.
