Duplicate Mac Address - Port Security

clear mac-address-table

conf t

int f0/2

switchport access

switchport port-security

switchport port-secruity maximum 1

switchport port-security mac-address 0002.4A10.9DE2

"Found duplicate mac-address 0002.4a10.9de2."

How is my Cisco switch finding a duplicate mac address when I cleared the mac address table? Anyone ever experience this before in Packet Tracer?
