Autocal Units won't switch from metric to standard

[JLaw297]

I tried to switch my autocal units over from metric to english but doesn't seem to have changed. I attached a picture of the page I'm on to change it. Is this right?? If I unplug the autocal and plug it back in custom is still selected but not sure why its still reading out metic units.
