Hello! It might be worth checking the users setups to make sure you do not have the following toggled on -- "Send work I assign to myself to my Working On tab"
In the highlighted part of your screenshot - it looks like it was assigned to a user and then changed to in progress. This could be because the user may have clicked ‘Work on it’ when they received the assignment, which automatically changes the status to in progress.
If this helped you, please mark correct to help others : )
