Multiple Sensors for Single Switch Port

I am doing auto-discovery on a Cisco small office switch (SG300) and PRTG (20.1.57.1745+) returns with multiple SNMP sensors for each switch port.

Each port ends up with 3 sensors. The traffic looks identical and all 3 sensors report themselves as sensor type "SNMP Traffic 64 bit".

Are these just duplicate or are they trying to report different data? Is there any reason not to delete the duplicates? All of the ports are on the same VLAN, and are vanilla out of the box as far as switch configuration is concerned.

Thank you for you help, David.

David,

Are these the result of running multiple auto-discoveries, or just a single one?

Just a single discovery. I have data in here now - if I delete them all and re-discover will the legacy usage data be maintained?

Dave,

No, if you remove a sensor, it will remove the data as well. Can you open a support ticket, and send us screenshots of the multiple instances that get created after running the auto-discovery?
