Shelly 3em Double Counting Issue

Hi everyone, I recently installed a Shelly 3em behind my electricity meter to monitor my energy consumption. After comparing the cumulative values of the Shelly 3em with my meter over several days, I noticed something odd. The Shelly 3em is showing approximately double the energy usage compared to my meter. To troubleshoot, I connected a clamp-on ammeter, which measures roughly half the current that the Shelly 3em is reporting across all three phases. I don’t have any solar power fed back into the grid. Has anyone encountered a similar issue or have any ideas on what might be causing this discrepancy? I’d greatly appreciate any insights or suggestions!
