Charles' audit is fully right.

After some more review and local testing:
- would you be able to test with the latest NUT revision (2.7.4)? Note that
it's not mandatory, since no change here should be impacting your issue.
- the firmware revision is bad (ups.firmware: 9SX5Ki)
- I've tested locally with a 9SX (ups.firmware: 02.17.0040, previous
official FW) and the needed data is present
- I'm convinced that your issue comes from an outdated FW.
would you be able to upgrade the firmware of your unit?
If so, everything is available here (for Windows only though): h

I hope the above information will help you in solving your issue.
