Mysterious "static" mac on interface

Hello,

I recently came across an issue that I was unable to find else in other forums. I am currently running 802.1x on 4507 (Version 03.03.02.SG & IOS cat4500e-universalk9.SPA.03.03.02.SG.151-1.SG2.bin). Anyways when i attempt to put the command "switchport port-security" on the interface, I recieve a message saying "Command rejected: GigabitEthernet2/16 has static addresses." and when i do "show mac address-table interface g2/16" i recieved " 104 b4b5.2fd5.c4b7 static ip,ipx,assigned,other GigabitEthernet2/16." However, when I try the commands "no mac address-table static b4b5.2fd5.c4b7" and "no mac address-table static interface G2/16." I get "no static entries found." Has anyone seen or heard of this issue before? For now, I have just shut the interface and labeled it faulty, but I was looking for some type of resolution or explanation. Thanks!

Please run these commands and share the output:

sh run int g2/16

show switchport port-security Int g2/16
