Hello, for the first bug i found, player cant private message other player in-game

Step to produce :

• /msg player_name message
• /tell player_name message
• /w player_name message

All command above will respond with "No targets match selector"

For the second bug, i try to implement my own ban using command block and kick command

Step to produce :

• /kick @a[tag=banned] Banned!

The command will respond "Please povide the name of the player you want to kick"

For this command, its work before 1.17
