Do you display the field(s) conditionally? Wrapper in <aura:if isTrue=...> tag maybe? Your find returned a single record with that aura:id (so there's no "filter" on it, it's a single object, not an array) or it haven't found anything at all.

Go to setup -> debug mode, enable it for yourself and add debugger; to this code (or add a watch/breakpoint from the browser's F12 console)
