Error in Dashboard with specific cell

[martint17r]

I created this query in the Flux Editor:

from(bucket: "s10s")
  |> range(start: v.timeRangeStart, stop: v.timeRangeStop)
  |> filter(fn: (r) => r["_measurement"] == "txs")
  |> aggregateWindow(every: v.windowPeriod, fn: last, createEmpty: false)
  |> pivot(rowKey:["_time","good"], columnKey:["_field"], valueColumn:"_value")
  |> yield(name: "last")

and use a simple table to display the result. Everything worked as expected - see screenshot:

Using a Table element works - but is not the output I am looking for
