Stop displaying ticket number in reply

Stop displaying ticket number in reply

Hello, I tried contacting support several times but I didnt have much luck, the thing is, I am starting to use zoho desk but I want to choose in which department I get the ticket numbers displayed and in which department I stop putting them there whenever I make a reply.

The thing is that when I reply in the subject it displays Re:[## 166 ##] (No Subject) where [## 166 ##]  is the ticket number, and I want it to display it like  Re:(No Subject).

 I will be waiting for your response.

Best regards!
