[Albion] Watford game sold out but no seatmove upgrade options !

Usually when a game sells out , some season ticket holders Nd 1901 seats are listed by supporters that can't go. When I looked on the seatmove app it doesn't even list the game as an option. Anyone know why or am I looking at the wrong link ?

Apologies I'm not usually so thick ! Just wanted to see if I could upgrade to 1901 for the Watford game. There is normally a few 1901 seats listed for sold out games
