Canada Visa

Dear Community Members,

I had applied for tourist visa with my parents from USA. Following are the timeline:

Application submitted: 6th Aug 19
Biometrics Collection Letter: 7th Aug 19
Biometrics Completed: 21st Aug 19

For both of my parents its showing below when I goes to: Check full application status > View submitted application or upload documents.

Family Members

You have told us that additional people will come to Canada with you. Please attach their documents below.
---------------------------------------------------------------------------------------------------------------------------------

Now I am confused for below reasons:

1) I had already uploaded the mentioned document when I submitted the application.
2) On my parents' dashboard table its still showing "We do not need additional documents" under "Review of additional documents"

So my question is what to do, do they need additional documents or not. If yes, then how to submit since there is no option to upload it as I had already uploaded the asked document with original submission.

Thanks a lot for helping hand.
