I replaced the trigger work item with another item in the prefab and saved it,
It is not saved.
I'm not sure I fully understand the problem. Can you please elaborate a bit and back it up with some screenshots or video capture?
1. Open the prefab.
2. Put an action in the trigger or change it to another action.
3. Exit the prefab.
4. When re-entering the prefab, it was not saved.
Even in a prefab with a dialogDeleted line 1 line is not saved.
