D-VO - if you want to see whether it's the defogger switch or not, remove the isvisible=0 line (that basically means you don't see the value in the log). That will let you know if it's switching or not - I'm pretty certain it is the right value.
I have a theory - in Vgi's logcfg, the addresses are ordered contiguously, which follows the request to sortpids = 1, making for faster logging. Yours are not - maybe that's the issue.
