Hi! We also have project templates I created, and I noticed the same problem.
So I’ve remove myself as a project owner. I was thinking that, as an Administrator, I would be able to take back the control of these projects anytime. But, when I tried to edit one of our templates, I was unable to do it! And now I read this subject, and also that.
So I don’t know what to do. @Marie could you help me with that ?
