Deleted list column not showing

Hi,

i had a request to find out who deleted a certain list column.

So i searched the audit log - but did not find anything.

I then created and deleted a list column in my test Teams. What i can see is the creation, what i cannot see is the deletion of the column!?

But the activity is there: https://learn.microsoft.com/en-us/purview/audit-log-activities#sharepoint-list-activities

What did i wrong?
