Getting on the train from Edinburgh and 4 of my 5 tickets have downloaded but one is saying “no up and coming matches” is there anyone best to contact to help around the stadium?

Where I’ve put the navy arrow, there’s a Fan Support Office in a cabin between spirals J and G of the East Stand. Don’t know what time it opens pre-game though.
There are people in blue jackets with signs saying ‘HOW CAN I HELP?’ dotted about the stadium grounds on a matchday n’all.
EDIT- just noticed on the image, there’s another one facing entrance R (depending which is nearer to where you enter the grounds).
