Rollover based on volume too early

It seems I go through this once per rollover (quarterly), and I dread it each time. Please tell me if I'm doing something wrong here.

I've posted a chart which has the continuous option enabled, volume-based back-adjusted rollover. For two symbols (NQ and RTY), the chart is rolling on June 10, showing data for that day from the September contract. For ES and YM, it works as expected and is showing June 10 data from the June contract. The way I understand, rollover based on volume uses the volume found in the daily chart. Here are the entries for June 10:

F.US.ENQM21: (NQ, Jun 21)
2021/06/10, 13817.00000000, 13976.50000000, 13726.00000000, 13959.75000000, 492336, 226362

F.US.ENQU21: (NQ, Sep 21)
2021/06/10, 13809.25000000, 13966.25000000, 13716.25000000, 13950.75000000, 53142, 30188

So, a chart of Sep should show June 10 data from the Jun contract, not Sep.

What's going on? I have attached ES, to show that it is rolling over on Jun 11, and NQ, incorrectly rolling over on Jun 10. I have displayed the rollover date for easy comparison.

The problem is very simply that the NQ chart is set to the September contract and that is not the active contract month. You need to change it back to June. This is explained at item 3 here:
