When you put a task or a milestone done, you should put some words in NOTE to provide more information for the task.
It does not mean that you change the task/milestone from Open to DONE, then your duty is done.
Some tasks also require you to upload the file as well, Please read your template that I have sent out. Even the generic template states very clear and details in TASK EXPLANATION and PTS MAKER.
For Milestone, Can you please also change estimated END date in milestone to match with actual end date you input?
