Task and version status permission

Hello All!
Hope you all have another great day.

I am trying to make new permission group - Senior Artist - based from Artist. (Shotgrid default)
So the only two diffences from Artist permission shall be able to edit Task & version status.
I checked all check box regarding task & version status but still it is unable to chage those status. Below are what I’ve checked in premission-people menu.

What should I check more to give them task & version status edit permission?
