Wagon air suspension dropping overnight?

I picked up a ‘14 E350 Wagon a couple of months ago. I’ve noticed, in the mornings, that the rear suspension has fully dropped down. Is this a leak, or normal/expected behavior?

Not normal, check compressor electrical harness if fine, see attached bulletin. Air spring rear left is current part # 2123203925, right 2123204025; valve unit 2123200758.

Thanks! It’s under warranty, so I’m working on a list for my first trip to the dealer...
