Only on one of my units does the Grid Graph go the wrong way .
I assume this is a VRM BUG
Not a bug, but an often misunderstood feature.
When there is both import and export, the graph changes to make it clearer which is which.
Export is to the left of the centre line, import is to the right.
When there is no export, only import, the graph will be the same direction as all the others.
