Right now it redundantly shows the username.
Example:

Are you using some chat plugin? from what I could tell, DiscordSRV just takes the message from the chat event, maybe your chat plugin is adding that to the message?

Yeah I'm using a chat plugin, maybe it's adding to the message instead of the format or something

as far as i could tell, no format was applied to webhook chat messages

could you create a debug? using: /discord debug

The cause was my chat plugin, I fixed it. Thanks
