When a Thing is renamed and propagated to SharpTools it does not automatically update the name within the rules. There it still appears with the old name.
When you edit the rule you can see the name of the thing is changed within the picker list but if you select the new name it does not apply it. You have to select a different thing, save it. Then edit it again and select the original thing with the new name.
If that is not clear send me a e-Mail and I’ll send a video.
