So I've been calling for 3 days now. Found out my 1K status actually processed in this last Sunday night 5/10. So on 5/12 when they deleted/re-added and PR-EXEC still showed up on the reservation, they said call back the next day and the 24-48hrs would have cleared and all would be fine.

On 5/13. Same story.
On 5/14 just now, same story.

They tried to tell me that reservations 'auto-update' with the status change...but then they said it still showed PR-EXEC. Mileage Plus 1k desk says '1k', reservations says '1k', itinerary says PR-EXEC.

last hope is to call tomorrow. Maybe then the '4 day window' referenced in other threads takes hold and it'll actually work... who knows.

Open to any other thoughts anyone else wants to share - otherwise, i'm resigned to PR-EXEC for another international trip, I suspect.
