Cannot remove "_start" and "_end" dict from column name

For some reason unbeknown to me, the following code changed behavior overnight and I can no longer rename or add a new column without influx appending a dictionary containing the "_start" and "_stop" values.

from(bucket: "snorkbench")
  |> range(start: v.timeRangeStart, stop: v.timeRangeStop)
  |> group()
  |> aggregateWindow(every: 1d, fn: mean, createEmpty: false, timeSrc: "_start")
  |> fill(column: "new_column", value: "column value")
  |> rename(columns: {"_value": "new name"})
  |> yield(name: "mean")

I’m using InfluxDB within Grafana and this worked fine a month ago, what am I doing wrong? I simply want to rename or add a column without this dictionary getting appended.

Hello @bradley.fowler,
This doesn’t happen in the influxDB UI. It seems like a grafana problem.
Can you please try and ask here?

Thank you!

Ah I see, thank you for your reply. I’ll ask on there.
