Chat Bug (PS3)

Every time I type anything in to the chat box it tries executing it as a command and says "this command is not a valid command."

ISP: Time Warner Cable

Type of Internet Connection: DSL

Internet Connection Speed: 20Mbit/s

Time & Day: 10/18/2013 Aprox. 11:00pm

Frequency: Always

World name: Coeurl

Character name: Erik Cartwright

NPC Name: N/A

Monster Name: N/A

Class/Level: PLD lvl. 31

Party or solo: Solo

In-game time: I don't remember

Area and coordinates: Ul'dah. Don't remember the coordinates but it happened everywhere in Ul'dah and everywhere in Horizon. (Those were the only two areas I've had a chance to test so far.)

Steps:
1. I was running around Ul'dah beginning to start the "All Saints Wake" event and I tried typing something into the text box, then receiving the message "this is not a valid command"
2. I then tried to use the "stock" in-game "keyboard" with my PS3 controller instead of my bluetooth keyboard and still, the same message.
3. I then made sure I had no "/" characters anywhere in my text, there was not, I then tried to restart the game and still had no luck in fixing the issue.

...will update with PS3 Model Number when I get off work and get home.
