Groupchat {{char}} problem

[koshaaass]

There is an issue where the {{char}} symbol is displayed as the chat room name, not the character's name, when sending a prompt in a group chat (confirmed by log). Moreover, If I leave the chat room title blank, {{char}} is displayed as a blank in the log, and if I make the chat room title {{char}}, {{char}} is sent as is without conversion to the symbol's name. Below is a partial capture of the log where {{char}} has been changed to the chat room name.
