Corrections

- "Select the screen timeout after waking up.": This is tricky, it is not the normal timeout, but really only applies after a wakeup event
- "Off. Requires ..."": The neighboring options all say "Disabled". Would take code change to alter this.
- "Let the system decide screen timeout": Too long and clumsy for the option screen
- "GPX file is damaged": Could be a false statement
- "Minutes until data expires:": this sounds like it would state the remaining validity, but I think it simply states the original lifetime
