In the Edit mode I try to define a new role. But after I create a new role it appears not for the selected Thing, but for the last Thing in my list of things.

Initial conditions. Anything worked well. I defined some roles for different things. The last successful creation was for the “Wizard” thing (the last thing in the list).
