The German translation (not only for the 1040) is wrong
"Grade" schould be "Steigung"
Currently it is "Neigung" which means "Descend"
If feels demoralizing when I climb a Grade of 10% and the Garmin shows me that I should fly down right now :-)
P.S. If there is a better place to report bugs then please let me know (I searched and couldn't find any information)
