Dispositivos duplicados

Hi!
I am experiencing issues with devices appearing duplicated in the Sophos console. The users affected by this issue have the same device (same serial number) but with a different operating system, which usually occurs after an update, and they show up as duplicates. I would like assistance in troubleshooting why these duplicate devices are being generated, considering we do not use gold images to install the agent on computers; instead, we do it via email.

Additionally, I would like to know how I can efficiently detect duplicate devices without having to check user by user. Is there a way to export a list of computers with their serial numbers? I don't understand why Sophos doesn't have this feature.
