Applied for 2nd extension but left canada

[annie464]

hi my parents applied for 1st extension and got approved until October 6 2020 but flights got cancelled and applied for 2nd extension and in the meanwhile they got back to India but 2nd extension application is still pending
left Canada on 6th November so i applied for 2nd extension now my question is should i need to withdraw 2nd extension application or should i need to ignore?
what else if i withdraw the 2nd extension application are they considered as illegal stay after 6th October?

please help me i am confused
