aye, I've done that before too! I think it is a bug, just not a very important one. Certainly not a useful one. I wonder, can you save the profile like that? Does the trigger still fire? Even when all other triggers/aliases are turned off via the bottom right button?
Yeah, that'd be a known issue... although sometimes I've noticed that they don't get saved through restart. For when they do, for loop to the rescue :/
Yeah, it seeming to be in the 'root' element. I think them being added to an invisible sub-element was a fix for some of the crashes people could get at some point... perhaps it was this case even and it's been fixed now, but the default stayed.
I don't think it has any bad effects, but I didn't test the trigger I had it so that time.
