PlayerSelector on slash commands is not working properly

PlayerSelector is working properly in client worlds as I tested. However, when it comes to Bedrock Dedicated Server the property of all commands including customs commands with PlayerSelector is not working as expected for non-operators.

For example, a player as non-operator could not use /w, /tell, /msg built-in slash commands because of an error or bugs even though they are only using the player’s gamertag. Furthermore, it also happens on custom commands with PlayerSelector enum making this property useless in Bedrock Dedicated Server.

I’ll provide an video below:
