I have found similar questions but they seem dated and don't seem to apply to my case unless I'm missing something.
Basically, I am seeing a lot of cases (most) where I am seeing "anonymous made a transition" entries under the "All" and or "Transition" tabs for issues. An immediate example was where I was making these transitions. I moved an issue from To Do to In Progress, commented on it and them marked as Done. Here is what I see in the activity entries in the ticket:
ALL tab:
- I made changes from To Do to In Progress
- I added a comment
Transition tab:
