Just to update people on this puzzle... I found a decade old backup, this item has the 10 PO items. My theory is way back some long time ago there was a PO demo (however no data exists now) and this item was the test subject and never got cleared out. Client is good in knowing confidently there's nothing that they did recently to cause this, and I can't see how this would replicate itself on any other products going forward we're going to mark this as solved.

Have a great week all!
