Content log spam on server join/switch worlds & command suggestions not working ([Commands][error]-Keywords in commands need to be lower case. '<argument>' was not registered.)

Describe the bug

When a Bedrock Edition client joins the server, changes worlds, respawns (side bug-the respawn screen appears twice, but that's separate), or gets opped, their content log gets filled with many messages that follow this format:

[Commands][error]-Keywords in commands need to be lower case. '<argument>' was not registered. where is a command argument that has at least one uppercase letter (e.g. 'doWeatherCycle').

If the player has the Creator > Enable Content Log GUI option enabled, it fills the top half of the screen with these messages for a few seconds.

(As implied by these errors) these arguments do not appear in the command suggestions, instead 'default' does.

This bug could also be related to an issue I noticed where the descriptions of most of the commands are the same, but not necessarily.

To Reproduce

(if Enable Content Log GUI is disabled) Go to Settings > Creator and enable the Enable Content Log GUI setting
Join a server or switch worlds in a server
Error fills up top half of the screen

Expected behaviour

There should not be an error, and the uppercase command suggestions should appear (probably converted to/from lowercase, as it seems that uppercase letters do not work).
