I'm the person who nominated Bray Wyatt and The Fiend Bray Wyatt. In WWE kayfabe, The Fiend is a separate personality of Bray's, so they can indeed be treated as separate characters and are from separate points in Bray's WWE career.
The nominations for Bray with Sister Abigail are from the days before Bray adopted the Fiend persona.
Hope that makes sense!
