World Import Failed With Mcworld Files

"Import level failed" error occurs when trying to open a MCWORLD file with a Minecraft World in it that you make through minecraft.

Steps to reproduce:

1. Create a minecraft world
2. Export the world to your computer
3. Attempt to download by double-clicking on it or using the import world feature in the Minecraft Bedrock game

Observed results:
You try to import the world, but you get the error "World import failed"

Expected results:

Correct world import.

 

I have noticed that when I downloaded the world, they take up 0 KB of storage on the computer. Below is the world that I have just made but it doesn't have any data on it apparently so it won't actually show. Here is a video of thwe world that I tried to download.
