Column Override breaks Flow graph

[MauriceHartmann]

Adding column Overrides can potentially break a graph.

An example:

column: {
          Oil: 0,
          Oil1: 1,
          Air1: 1,
          Air2: 2,
          Stuff1: 1,
          Stuff2: 2
        },

With the following Dataset

data: [
          { from: "Oil", to: "Air1", flow: 15 },
          { from: "Oil", to: "Stuff1", flow: 20 },
          { from: "Oil1", to: "Air2", flow: 25 },
          { from: "Oil1", to: "Stuff2", flow: 25 `},]`

completly breaks the graph, as shown here:

How I would expect it to look (without the crossed out flow):

{ from: "Oil", to: "Oil1", flow: 15 }, was added for screenshot above

And Thanks for your hard work!
