[Observium] Event log showing 'changed' entries every 5 minutes

Hello,

We're running Observerium Professional 21.10.11636.

Every 5 minutes the same 'changed' entries show up in the event log (screenshot below). The device in question is a Cisco ASR9K. Browsing to the device's page it looks like the changes below aren't actually be applied (no serial number listed, hardware is generic).

How can I go about fixing this?

Thanks in advance!
