Great news then @SKD
I will check the status field from v5 data and provide a solution for v7 too (not for you anymore but for future Legacy Imports).
Enjoy v7
Side Note: Status should be ARR (ARRIVED) for v7 pireps, it is designed like that. When a pirep is finalized/closed by the pilot, it gets this status. So we should set this for imported pireps, even if they are rejected, they should be arrived. Thanks for sharing your findings on this.
