stain finished but still visible

I am coming to you because I cannot find a solution.
let me explain, a spot is made a colleague, and he has several other spots which are assigned to him.
He was creating a subtask that he told me.
this task is carried out once completed and I select it as “done”.
So my task is finished but there are still spots for my colleague.
Why in my personal space I still see her.
While it is well selected as finished for me …
Thank you for your help.

you may want to try using visuals, your English is hard to understand.
