Discrepancy between Marketo Logs

We've recently had an email released to an incorrect audience. When we talked to support they showed us the issue, but we don't have records of that user in our Admin Audit Trail logs making that change. Also, on our screen, we see the correct filter logic applied (using ALL filters) but on their screen, the discrepancy is someone changed it to (ANY) filters. We know we didn't touch that filter logic when they said we did as we were on a team call discussing something.

Has this happened to anyone before where there is a discrepancy between what support says and what your logs see from the Admin Audit Trail?
