How to remove a template that I added to the backstage?

I clicked the "Add Template..." button at the top right of the backstage view. My template was then added to the list of available templates under "My Templates". Now I want to remove it, but can't find where these are stored on my system. I looked under "My Maps" and also under %LoadAppData%/Mindjet/MindManager/23/Library/ENU/Templates, but there is nothing there. Apparently MindManager caches these somewhere else?
