Can’t find IPs from WAF alert email

I received a Wordfence Increased Attack Rate alert email that read:
“The Wordfence Web Application Firewall has blocked 175 attacks over the last 10 minutes. Below is a sample of these recent attacks…”
Then for 10 samples, it lists date/time, IP (unknown), attack description: URL

I’m not able to find any of the attempts in the Live Traffic view, filtering by time or IP.
I appreciate the help investigating this.
