ProceduralGridMover Error

I use ProceduralGridMover to update LayerGridGraph,but it was misreported.Log entries " Grid Graph is not scanned, cannot update" .
I found the graph.nodes is more than widthdepthLayerCount (graph.nodes > widthdepthLayerCount).
The version is 4.3.47.
How can I deal it?

Would it be possible to upgrade to a newer version? That version is quite old.
