If the final is blank, then a decision on your application has not been made. If you are an outland applicant, then many applications for outlander applicants have been put on hold since they are not exempt from the travel restrictions. IF a decision on your application is made, and a PPR / COPR issued, then the status of the application is closed.
However, if you are unable to travel before the cOPR expires, then an application has to be opened and a final review has to be done again, including extension medicals and in some cases security / criminality.
This is why many applications even if all stages are passed, a decision has not been made and they are open.
