Flux function increase() skips data

[Maxime]

When using the increase function, the function sometimes skip some data making the result false:

This is the raw data:

Expected result should be 41, instead we get 40:

I tried to put the same data twice, and the two results were different (one value of 70 got skipped):

The request used:

from(bucket: "metrics_test")
  |> range(start: v.timeRangeStart, stop: v.timeRangeStop)
  |> filter(fn: (r) => r["_measurement"] == "test_categ" or r["_measurement"] == "test_categ2")
  |> increase()
  |> yield(name: "increase")

The version of our influxDB instance is 2.5.1.
