The "percent blocked" field displays a value in percent rather than the glancing "undefined" display. I am using pi-hole on my Synology NAS in Docker in version Pi-hole v5.3.1 Web Interface v5.5 FTL v5.8.1. The error occurs only after I have installed watchtower (https://mariushosting.com/synology-30-second-watchtower-install-using-task-scheduler-docker/) for updating.
