802.1X shows no MAC address on port

When 802.1X config is applied to the port I can no longer see the MAC address on the interface.  When config is removed the MAC address shows up on the port.  After applying the config I have bounced the port and the device however it still does not show up unless I remove the config.  Since the port never gets the MAC address we are not able to authenticate the port using MAB.  Here is the config applied to the port.

This is a 9248 switch running 16.9.4.

Try to configure the port with open authentication .use the following command 'Authentication open'.
