Not to add elevation thing in NOTE field?

It seems I used to have it turned off, but now WayPoints and Courses elevation correction puts the SRMT 1" blah, blah, blah, text in the notes field every import. How do I turn it off, or has this capability been removed? Perhaps I just don't remember where to turn it off, I looked thru settings in all 7 of my OMB plugins (!), but I'm pretty sure I used to have it turned off!!
Thanks,
Tom
