Yes.
I looked into this and I think what is happening is this:
If a plant is a parent plant and the databox for it is updated, the databox details is passed down to all present and future child plants.
But if the databox is already there, and a plant is subsequently marked as a parent, then the data is NOT copied down to past plants, but is copied down to future children plants.
I think that's what is happening here. I have resolved it by editing the databox again (without changing anything) and upon approval all the details should have been copied down.
