Vaccine Passport not showing up in wallet

Hi all. I have uploaded 3/4 family members vax passports to my wallet for an upcoming trip. The last one will not show up. I have followed all the same steps. I open it to health (where it doesn't show up) and then click add to wallet - and it says "Vaccination already added". However, when I go to wallet it is not showing up. I'm fully updated to the newest IOS and have done two hard restarts. Not sure what to do. Any help would be great. Thanks
