Yes, because express entry application is a lot quicker than paper based. That's why my wife filed another but express entry application when she received an ITA in the hope that the second one (express entry) will be processed earlier than my first paper based one. My main concern is that her application is still in progress and we don't see yet that her application is approved.Any reason for filing again ? typically, if work permit extension and PR under process, at the time of PR approval, IRCC cancels other application and refund fees. in your case, they would have already reviewed the same documents and performed background and security check through your application. I'd think they withdraw your application by mistake they should have withdrawn your wife application.
