rFactor 2 Help with Quick Chat

May I ask Which Keybindings (keyboard) do you use?

I tried setting some set up, but can not get it working. I can Vote and Ping whit assigned keys but not #Quickchat whit my assigned keys!

When pressing the key ex. "," for Quickchat #1 - only that symbol shows, not the assigned text for ex. Quickchat #1

 

Latter edit (put it here because I think I found your mistake)
DO NOT PRESS "T" for TEXT chat. Only the assigned key for quick chat. In this case press directly ","
Hi, I never used this feature. Now from curiosity I tried.
Working straight forward. Just start rF2, go to Controls/Chat. Assigned "," to chat #2. On track when I press "," the message "Leaving pits" it is displayed in chat box. I don't use any other software or key binding application. I don't know what to say. Maybe you can have a look at player.json file in X:\Steam\SteamApps\common\rFactor 2\UserData\player folder. Mine looks like this (I didn't tried to customize the messages):
{
"CHAT":{
"Quick Chat #1":"Slowing to pit",
"Quick Chat #10":"\/vote yes",
"Quick Chat #11":"\/vote no",
"Quick Chat #12":"\/ping",
"Quick Chat #2":"Leaving pits",
"Quick Chat #3":"Go Left",
"Quick Chat #4":"Go Right",
"Quick Chat #5":"Thank you",
"Quick Chat #6":"Sorry",
"Quick Chat #7":"Be careful at the first corner",
"Quick Chat #8":"Good job",
"Quick Chat #9":"Good race"
},

 

By this you mean with "T" key you activate "Voice chat"? I suppose this because of ... "Talk"
And for "Quick chat" you must assign 12 keys for the 12 quick chat messages you can configure in player.json (my previous post)
Sorry I edited my previous post "DO NOT press "T" for "TEXT chat"
