Spell Check -Autolevle
Found this a bit annoying so I found it. In uilang.h multiple times the spelling was "Autolevle Measure", it should be "Autolevel Measure". Not critical just flip the "le" to "el".
I just used the search and replace.
Could not find it. Which fork and version are you using?

My apologizes, I was using 92.9 from Zonestar. Current version is OK! Actually I could not find that line in the new version. It was a menu item on my LCD. I'll flash the new version and see what I get.
