Big fix needed please

Three family members flying on same flight record number this weekend, I checked in for all 3 using my app. All three of us have app on our separate iphones, all three are logged in to app using our individual FF/accounts, all of us pulled down our boarding passes and saved to wallet. When we return to wallet to go thru security/get on plane, two of us keep finding that saved wallet pass swapped out for the other even though it was initially on our own name. Love the app generally but this is a major bug, caused flight crew difficulty on initial leg as system seemed to think I was on twice and my son not on board. Has affected 3 of 4 legs so far.
