list the most recent value in a calculated table

Hello,

I have datasource where I list all audits performed to a project.

I then have a calculated table that filters out the last ones audited in the last 30 days. These are considered "recent". Using the formula below

= Table.SelectRows(#"Renamed Columns", let latest = List.Max(#"Renamed Columns"[AuditDate]) in each Date.IsInPreviousNDays([AuditDate], 30) or [AuditDate] = latest)

But it snaps when a project is audited that was still within those 30 days. This is because it is trying to add the same value twice to in a one-to-one column.

How can I fix it?

Thank you for your help.
