What I expected to happen was...
When I downloaded my Realm world, it would be exactly the same as it is on the Realms

What actually happened was...
All of the blocks, chests, etc. were the same, but everyone's inventory was the same as it was the last time I uploaded a world.

Steps to Reproduce:
1. Upload a world to Realms with a dirt in your inventory.
2. Once in Realms, replace the dirt in your inventory with wood, and build a small structure.
3. Download your world to your computer.
4. Even though the structure you built is still there, you now have the dirt in your inventory even though you replaced it with wood on your Realm.
