The /fill command is not working well in Bedrock edition. Normally this command is used to change blocks in several coordinates

Steps to Reproduce:

1. Open the Minecraft Bedrock chat.

2. Put the command /fill and write in which coordinates you want to change the blocks.

3. Choose a block you want to place in the coordinates by.

Observed Results:

The command simply changes one coordinate block.

Expected Results:

The command should change the blocks of the coordinates you chose equal to the Java edition.

I left a video of the different editions so you can see what should really happen.
