I have 28 transactions that are not appearing despite syncing my bank account to QBSE. When I tried to add them via CSV, they were "already detected." Where are they?

It seems like QBSE knows about the transactions if it is warning me that the CSV contains duplicates, but they don't show up anywhere in QBSE. I have two WF accounts and a CC which are all missing transactions for identical date ranges. Any insights are appreciated.
