Auditing Resource Bookings

I am once again dealing with overlapped bookings on rooms set to not allow overlapped bookings. I've verified this in PowerShell. I've limited who can make these to 2 users. I've trained these users. They are using Outlook on the web - just in case the app doesn't update. STILL, I am getting bookings on top of each other. One person books something - then another person books something on top of it. I need to audit this. I have enabled resource auditing. I have tried 

1) Purview auditing the booking users - everything they do related to Exchange. This returns hundreds of entries for the time periods specified, and I genuinely do not have time to parse all of this.

2) using purview to search only for entries on the room resource. These apparently have no data, ever.

3) Using purview to search for activities related to booking.. Too bad the activity dropdown does not work, and 80% of the entries are repeats. Maybe I can find operation names from the documentation? (no)

4) Maybe Copilot can help me find operation names? (no, he just hallucinates)

6) Abandoning Purview, I open Exchange and head to the Collect Logs entries. I run both Resource Bookings and Calendar logs. Because that is, essentially, exactly what I want. Unfortunately neither of these are even remotely useful to a human - except to confirm this shouldn't be possible. I spend an hour parsing through the endless nigh-identically named fields, to find data relevant to me - What I can find isn't accurate, and isn't useful. 

7) I open Outlook, and try to look at the actual mail interactions on that shared mailbox. Unfortunately, there is nothing for these days. No sent,  inbox, deleted items referencing the bookings at all. 

8) I open powershell, i try commands microsoft gives. These are deprecated. 

This should really not be this hard. In fact, it should be REALLY EASY to see when bookings came in and out. I am really close to looking for a 3rd party solution just so i don't have to waste any more time on this
