Are you still having this issue? I'd need a little more information, such as what your config looks like, example messages that users typed, etc.

this come on all messages. if i use Babel and BabelChat i give you the configs:

{
  "Force default server language (true/false)": false,
  "Log chat messages (true/false)": false,
  "Show original message (true/false)": true,
  "Use random name colors (true/false)": false
}​

config/Babel.json
{
  "API key (if required)": "myapikey",
  "Translation service": "yandex"
}​

config/UFilter.json
{
  "Check for advertising (true/false)": true,
  "Check for profanity (true/false)": true,
  "Check player chat (true/false)": true,
  "Check player names (true/false)": true,
  "Log advertising (true/false)": true,
  "Log profanity (true/false)": true,
  "Log to console (true/false)": false,
  "Log to file (true/false)": false,
  "Warn player in chat (true/false)": true,
  "Action for advertising": "block",
