If you're seeing assignment due dates from a previous school year, this isn't an error with your account — it usually just means your teacher hasn't updated pacing for the new school year yet. There's no late penalty, so nothing is being held against you in the meantime.
For Students
Reach out to your teacher and let them know you're seeing due dates from last year. They'll need to update your pacing so your To-Do List reflects this year's schedule instead. For more on how due dates and your To-Do List work, see How can I see when my assignments are due?
For Educators
Pacing dates don't automatically roll over between school years. If a returning or promoted student is seeing due dates from a previous year, update pacing for their course to reflect the new term. For step-by-step instructions, see How can I set pacing?
