3. Go to the issue interface of the repo
4. Click the "+" button to create an issue（or edit an existed issue）
5. Click "milestone" and try to add a milestone

If you never add a milestone for the current repo before, the box is empty and provides no function

If you have added milestones for the current repo, you can only choose from the added milestone but you cannot edit
