Dell N3024F loses IP OSPF AUTHENTICATION SIMPLE command on reboot

Dell N3024F firmware version 6.2.6.6

Configure a VLAN interface with OSPF

Use the command IP OSPF AUTHENTICATION SIMPLE password

When you run the show run command, the password (or key) displays as encrypted.  The OSPF network connects and runs as expected.

When you reboot the switch, the whole command disappears from the configuration.  The OSPF connection does not work.

I don't get it.  The N4032F at firmware version 6.2.1.6 does not work this way.  Does anybody have any clues for me?

Downgraded to firmware 6.2.1.6 and command works as planned.  Seems there were some firmware changes that broke the SIMPLE version of the command.  I'll hand this one off to Dell.
