I have this escenario with 4 swirches on a single stack cofiguration.
When I type Show MAC un a specfic port, I got several MAC addresses. but they are physically 1 computer by port
ARP table is populated dynamically..
I cleared the ARP table and after around a minute it gets full again.
RSTP is enabled

Have you verified to make sure that this computer is not running any type of virtual machines (VMs) or virtual adapters? If it's running VMs in something like VMware Player or VirtualBox then you will see multiple MACs (assuming the VMs have the adapters in bridge mode).
