If there's an upcoming events block or calendar block on your course homepage, you can see upcoming deadlines in this block. By default, deadlines occurring in the next 10 days are shown. When you complete an activity, the deadline message related to this activity may persist on the upcoming events or calendar block. It won't disappear until the deadline has passed. Please don't be concerned by this. To check whether you have completed an activity, go to the activity page to check if your work has been submitted or see whether a completion check mark has appeared against that activity. (For peer assessment activities, see this: Phases of a peer assessment activity)
