If it's related to Todoist, then it must be because you installed an application or browser extension or similar that links your Todoist account with your HabitRPG account in some way. HabitRPG itself does not know that you are using Todoist and HabitRPG itself is not creating this habit - the third-party app/extension that you installed is. You just have to find the app/extension that you installed and uninstall it. It's the app/extension that is doing the communication between the two.

Note that there are other third-party tools that integrate HabitRPG with things other than Todoist, so if you haven't installed anything related to integrating HabitRPG with Todoist then you'll need to look elsewhere as well. Some of the apps and browser extensions that people have built are listed at http://habitrpg.wikia.com/wiki/Category:Extensions and http://habitrpg.wikia.com/wiki/Category:Apps
