Have you considered buying the game?
This occurs when the Bundle / Shulker Box is destroyed by multiple fire blocks at the same time.
This is intended. As of minecraft 1.16.2, execute in respects dimension scaling, meaning that overworld coordinates are divided by 8 when executing in the nether.
This is because the NBT tags for setting a block with a loot table and giving an item with a loot table are different. For a block it is: /setblock ~ ~ ~ minecraft:chest{LootTable:"name"} and for an item it is /give @p minecraft:chest{BlockEntityTag:{LootTable:"name"}}.

Zombies can still pick up items in 1.15.1. However, not all of them can. The chance that a zombie can pick up items depends on the difficulty.
Affects 1.15 pre-release 6.
Still present in Minecraft 1.15 pre-release 1.
Confirmed in 23w31a.
