The loot table of minecraft:archaeology/desert_pyramid doesn't contain the arms up pottery shard

When playing with the loot table of the new suspicious sand, you see that it misses the 4th pot shard.

What I expected to happen was...:
4 different pot shards must be present in the loot table of suspicious sands

What actually happened was...:
The arms up shard is missing (minecraft:pottery_shard_arms_up)

Steps to Reproduce:
1. Take a repeat command block
2. Enter this command : `loot insert ~ ~1 ~ loot minecraft:archaeology/desert_pyramid`
3. Put a chest on top of the command block

4. Activate the command block
