LOG_* parameters missing

Hi all,
trying to configure logging… target is a CubeOrange+.
Mission Planner however seems to be missing almost all the logging (LOG_*) related parameters?
help! John

No problem here with a CubeOrange+
What’s that showing you are connected to, COM6-VTOL DUORO?
Nevermind, Bicopter. The craft for people that like pain.

Ha yes, “VTOL DUOROTOR”.
Pain indeed, hence the need for logging.

Can anybody shed some light on how Mission Planner chooses which parameters to make available?

SOLVED.
Was using a very conservative (i.e. only the bits removed I was sure about) custom firmware build. Reverting to standard has fixed the issue.
