Hi, you need to click on Tools - Options - To-Do list format. You'll see that 'Encode project name' is checked. In the 'Notation' section, you can define where this encoding is either 'Prefix' (in your case' or 'Postfix' - the Postfix option lists the project name after the name of the tasks.
You can also define if the project name is, for example, bracketed eg put ( in Start string and ) in End string. This can help to separate the name of the project from the name of the task
Hope this helps
