Upcoming passes disappearing from Wallet

Twice in the last two days I’ve had upcoming passes disappear from Apple Wallet. The other day it was just a pair of concert tickets so it wasn’t a big deal to re-send them to Wallet from Ticketmaster. Today I lost a bunch of passes though (for at least 9 different upcoming events that I remember offhand but I think there were even a few more than I’m not remembering). These were all upcoming events, none were expired/past. I’m on an iPhone 13 Pro and I have downloaded the most recent update a few days ago. I’ve never had this problem happen before the other day.
