I have created a status to be used in our PM module called " Task Closed"

I have set the type to "completed"

When a tech is assigned a task in our PM module and has completed it, he is to set task status to " task closed".

The problem we are having is when setting it the task status to task closed, it  does not remove it  from his task list. Only if he selects the status "closed" does it get removed from his task list. 

Is there a way use the "task closed" status similar to the "closed" status?
