Just claimed the Record Setter triumph as the last triumph needed to gild Champ, progress now says 20/20 but the title is still purple and not the gilded one, not showing as gilded in the seal menu either. Looks like the Hall of Fame and Record Setter triumphs don't have the same background as the other two gilded triumphs, not sure if that's relevant. I also had the Champ title equipped at the time of claiming the final triumph. Claimed on PC. Edit: just seen this on the list of known issues, plz ignore
