Junior ticket now showing on mobile pass

Hi all, I bought two tickets for the game at the weekend against Fulham. One adult ticket and one for my son as a junior ticket.

Only my adult ticket has been loaded to my mobile pass, when I try to add the junior ticket it says its already loaded but I can't see it on my google wallet, just my adult one.

Any ideas why this is? I checked for our last game last year and we got both tickets loaded to my wallet.
