Not able to see which device is going outside the VPN (and which device and requested domains)

I own a OpenVPN setup with a Pihole configured with NextDNS. All my devices are working inside the VPN (even my router) and with [seamless tunnel options/VPN always on] so that if VPN goes offline, internet for that device goes off as well; however from time to time in the analytics, I get my local IPs resolving, but there is no functionality to click on it to see which domains that IP was asking for, nor which device was. And in the logs, I have to be hovering the mouse over each entry to see the IP, which is an impossible task. I browsed through the "source" html and didn't find the IP's, so no easy way to search.
