Since both Dearborn and Kansas City are down the week of June 7th, I suspect your build date has already been rescheduled.

I'm thinking the same thing...This was in the article as well:
Most recently, the Ford Dearborn Truck Plant – which builds the Ford F-150 – was idle the weeks of May 3rd and 10th
Looks like your order was built in Dearborn and the stock order was built in Kansas City. It seems like more trucks that were built out of Dearborn are sitting waiting for components compared to the ones from Kansas City.
Where exactly did you see this? I've been only able to come up with this, which mentions Kansas City is closed weeks of May 3rd and 10th.
